I think I overdid something. I am in a lot of pain.

Any good lifting plan will tell you that high weights, low reps and rest days are key to building muscle.

You cant lift that much every day and not expect to get an injury. Your body needs to rest to heal itself.

Don't do any lifting until your arm feels better. An ache is fine, but actual real pain means you are doing something wrong, and if you carry on you will do yourself a serious injury.

Not only was I able to work out, I was able to increase the weights and do them with less reps as suggested here.

Thanks all for the advice.

With your arms huring more than the day before.....that might not be a good thing.

YOU NEED REST.

You need REST like EVERYONE ELSE SAID and if you do the same workout every single day or every time you go to the gym your muscles won't have to work as hard to do the exercises despite added weight or reps. DO some reading, do some research on RELIABLE sites, get a trainer, get to know your body and what it needs.

You need some rest. I understand your all or nothing thinking, but you're going to have to train yourself out of that or you're going to seriously injure yourself and have no choice. If going to the gym everyday is really a requirement for you, I suggest a couple of days be a 20 minute slllooooow walk on the treadmill with a good book, or a magazine, followed by a really good stretch. Or, if your gym has yoga classes, take a non-strenuous one (ask at the desk, they'll tell you which are designed for relaxation). Then you have kept your routine up by going to the building, but you haven't exerted yourself and added to your muscle pain.

honestly, i think you should talk to your doctor.
i don't think your mindset is healthy.
to me you sound obsessive and OCD about this whole thing.

I would recommend this.

I was planning on doing JUST cardio today but I ended up doing everything and even more because I felt that I would be slacking off and getting fat again.

Plus, I ate a handful of prunes today and I am still feeling guilty because they were sweet. If I didn't work out I couldn't handle that.

Yeah, that's a problem. You need to talk to someone about your obsessive tendencies.

I am talking.

Here.

I have received only laughs and doubts from people when I said that I am going to diet, so there is no way I could talk about this stuff in person to anyone.

Then maybe stop talking and start listening as you have apparently ignored everything everyone has said so far!

If you absolutely have to work out everyday, then you need to do a split body plan that allows each muscle group to rest before you work it again. Or you will strain something badly (or worse), and it WILL put you out of action for weeks or months. Is that what you want?

Don't just train harder, train smarter.
