Looking for Advice and motivation

I have gone through something similar. I ended up with anxiety and depression because of what I was going through and never wanted to leave the house. My therapist told me the best thing I could do was first cut out all caffeine. You are already getting jittery from what ever it is your dealing with. If you can't do it cold turkey, start slow and ween yourself off gradually. Try using tea as a substitute, no coffee, sodas, or anything else that has caffeine. Get decaffeinated tea. There are some surprising varieties that are really good. I personally quit using sugar, I only use honey instead, but not too much, it's healthier and if you get local honey it'll help with seasonal allergies. Give it a couple of days, you'll be surprised how much it helps.
Try looking at what you eat. I cut out almost all carbs (anything made with flour) for the time being. Try to find veggies that you love. I bought a steamer and steam my vetables, it tastes better to me. I eat a lot of broccoli because that is one of the few veggies my son surprisingly loves, steamed of course.
But the BIGGEST thing that helped me change is writing down everything that I eat, write while you eat or just after, no matter what you're eating, just write down as much as you can until it's a strong habit, use a journal or use the MyFitnessPal app, don't worry about calories at first, just focus on the habit. I built the habit into my daily routine and now I feel guilty if I missed a meal so I sit down and right what I can.
Start with foods that are simple to make, I've tried almost every diet and eating plan that exists, and the best thing I found that helps is to find foods that you like that are simple to make, I eat oatmeal every morning with cranberries and brown sugar.
The second thing is to get a journal and everyday right before you go to bed, write what ever is in your mind, doesn't matter what you write, just empty your brain. You might feel a little drained, you might cry a little, you might feel something else, but you have released everything that has built up that day. You'll sleep better when you've talked to someone, even if it's just a book.
The third thing that I found has really helped me, when I don't feel like exercising or have no motivation to move, I stretch, use poses that are easy for you and just do them while watching tv, or just get up and move something simple; swing your arms as much as you can till you get tired, or walk slowly, even if it's just to the end of the street and back. As long as you start with building the habit of getting up and moving constantly for as long as you can, start with 20 to 30 minutes. Walk around your home, vacuum, sweep, any movement will do. I depend a lot on music. I've been building an inspirational play list with the most upbeat songs I can find, songs that make you feel good or make you want to dance; the Fight song, We are the Champions, party songs; I'll put the play list on Spotify and put a link on here. If you like Christian music listen to Klove.com radio. You can find a local station that broadcasts for free on the radio.
Try self help books, I'm reading one now that is funny and speaks differently, You Are ABadass (that is really the name of the book). I was very surprised and excited to read this one because the author speaks differently about what to do and how to do it.
