Oh, regarding pcs and using computers: look up something called bi-nasal occlusion. You put tape on your glasses basically. It's helped me a lot, my OT told me about it. I can't use a computer without it for more than an hour or so.

She also recommends a weighted pressure vest, but I've only tried it for a day or two. It helps you to focus, but you will stand out a lot, which is socially awkward. I don't know. I will maybe try it again...

Neither is a miracle fix, but the binasal thing especially does make a noticeable difference. It doesn't make you feel good but makes it take longer for you to feel bad.
