Nonverbal/Partially Nonverbal?

I've always had difficulties with speech, it's a psychological thing, though the amount this has led to me being nonverbal or otherwise outwardly visible impediments has varied. For me it's primarily a psychological thing, though I have some throat difficulties which can certainly make things more difficult at times.

When I was younger I'd estimate at being nonverbal around 40% of the time, speaking was exhausting over half of the rest, and I honest to goodness could not speak louder than a whisper. From when I was around that age I guess what I remember most is being shouted at a lot to speak louder, or speak, or participate better, or ar-TI-cu-late whenever I was trying to communicate with someone which clearly didn't help and just led to me isolating myself, not speaking a lot of the time even when I thought I would be able to, and spending most of my life so far doing my best to hide the fact I can't always speak. I also had a kind of 'reverse lisp' in that I had a lot if difficulty saying 'th' instead of 's' which still comes out when I'm verbal but tired or having trouble speaking.
Generally it took me a long time to learn how to pronounce words too since I had only learnt most of them through reading and didn't (still don't honestly) understand why some differences mattered when it was just a matter of region and country how it was said being bilingual. I don't know if this is a common thing in more verbal folks too though.

Socially, during primary school the teachers pretty outwardly labeled me as stupid, extremely shy, quiet, nonparticipating, or antisocial depending on the person and it kind of ended up in a while of being bullied on all sides. Eventually I ended up finding a few ok teachers and made friends who got used to that I wouldn't always use words to communicate and who I had a lot of fun with but it still continued in many ways until I left regardless.

In high school I'd usually just escape to the grounds or computer lab to talk to people via text format or otherwise just quietly sit with friends I made when I wasn't able to or otherwise didn't feel like I was up for talking. They got used to it, and even outside of being nonverbal I was kind of shy so people just saw it as a part of who I was, though it was sometimes an issue since I couldn't make verbal calls in team activities in gym and got in trouble from having to pretend to not know the answer to things or being unusually quiet in presentations. This was around the time I was finally discovering my passion for writing (delayed unfortunately by primary school labeling as 'too stupid to write' and similar) and I also just spent a lot of time focused on this so being verbal was less of an issue. I just didn't need to nearly as much anymore, and in high school I'd managed to develop some good initial bonds with teachers and bullying had shifted more to other aspects of me so that wasn't as much as an issue anymore either.

And then we get to sixth form, where going nonverbal started to have more of an impact in classes and while trying to talk to teachers. This is where I finally started getting accommodations for things.

I never got any accommodations for the majority of my schooling, my parents didn't want me to be diagnosed and even went so far as to hide from me that the possibility of my being autistic had been mentioned before when I'd started to try and suggest things after having developed an interest in psychology and noticed a near exact number of matches in the diagnostic criteria. At 16 though in England at least I was allowed a lot more agency in such things and started seeing various psychs and communicating with my teachers and the diversity head in order to get accommodations since while I didn't manage to actually get a diagnosis for things covering going nonverbal until the next year I did clearly have issues and as it turned out that was enough to get some things.

Which was good because it was from around the second year to now that I ended up becoming around 80-90% nonverbal, and so this brings us to college.

Now, I'll admit college accompanied an exponential amount of more situations in which being nonverbal would be an issue which I didn't have to deal with in my past schools - I could usually just avoid a lot of them and spent a lot of time alone so it's entirely possible that the amount of time I'd been nonverbal had been increasing beforehand and I just didn't notice since I'd gotten so much better at subtly using other ways to communicate and avoiding predicaments in which it would have caused an issue/been obvious in general. But either way as the first year rolled around it came to light that I was starting to be nonverbal around 70-80% of the time by the end and by this year it's become 80-90%. So yeah, it wasn't something I could even try and hide anymore.

I started using an eraserboard or my phone primarily to communicate in groups I attended, and started notifying teachers in classes it'd be relevant or if I wanted to communicate with them enough (or needed to for any reason) that I'd prefer to get through my anxiety about telling them than stop talking to them as a result. Now I have my diagnosis too (being nonverbal and variations in this being included) I have an accommodation to make sure professors let me use a word processor or eraserboard in class and so that I can get accommodations in verbal based assignments. I've had to provide all of my materials myself, and so don't have a tablet or anything even though I'm sure it'd be a lot easier than my eraserboard and phone. It's been a lot of work working with the admin on this but I managed and in all honesty I'm a lot happier now than I ever was when I was more often verbal and/or trying to hide the times I couldn't speak.

And that's pretty much a summary I think. I'm sorry that first part in sounds pretty dire but I couldn't really find a way to separate all of those kinds of things out from my experience in being nonverbal since it's so interlinked with each other.
