Some "habits" I've dealt with for years and not been able to break include:
Typing/retyping..I'll delete the last few letters of random words and type them over and over.
Writing over words/letters to the point you can't make out what it says.
Getting stuck reading..it can take an hour to finish reading a page. I'll re-read a word a few times, then it turns into a sentence, paragraph, then I'm rereading the whole page or chapter. I used to love reading, now I get a headache just thinking of picking up a book.
If someone asks me a question, I repeat it in my head, sometimes multiple times, before answering.
I "twitch" my muscles. I've only recently noticed how much I do this. It's like my arms/wrists tighten up, especially when I'm still, not doing anything.
I kick my legs backward, like I'm popping my knees constantly.
I pop my wrists..to the point they feel shaky and sore.
I make this humming/clearing my throat type noise. Especially when nervous.
My thoughts feel stuttered. It's as if I have to repeat my thoughts halfway through a sentence, to the point that I feel exhausted.
My prayers never end. It's such a hard thing to do, just because it's so stressful, repeating things to no end.
I touch things repeatedly..walls, tables, etc.
I pick up and put down things over and over..cups, phones, etc. to the point of nearly breaking/dropping things.
People notice how obsessed with symmetry I am.
I'm terrified of germs. I rarely go in public. I freak out if I've been around someone who's been around someone who's been sick.

On the worst days, these things can keep me from falling asleep. It's usually around daylight when I fall asleep. I feel too tired to sleep. Just mentally exhausted.

These are just a few things I'm wondering if anyone else has done. Any advice would be appreciated. I just joined, so it's nice to be here. Thanks in advance!
