Weird phys and psych symptoms - Cause?

A little background - I have been diagnosed with Asperger's Syndrome, depression, GAD and OCD. I have been prescribed Xanax (for anxiety), Lexapro (for depression/OCD) and Risperidone (for suicidal/homicidal thoughts and gestures) and I have been taking them as prescribed since I was 14 (I'm turning 22 in a couple of months). Remarkably, I have had no major side effects from any of my medications and they have all worked wonderfully to treat my mental health conditions.

But for the past several days, my wrists have been feeling really tight, like if I were to bend them at all, they would snap. They used to only get this way whenever I saw something disturbing on TV or the Internet, but now they feel that way constantly. Sometimes they feel so tight that they hurt. I could have sworn that they looked swollen but when I asked my mom about it, she said they weren't. I've also felt like curling up in a ball and screaming for no real reason (no anger, anxiety, etc.) I'm also constantly drowsy/dream-like even though I've been getting the same amount of sleep as I always have, and I'm starting to forget to eat when I'm hungry, when normally I pig out on food all day.

I don't know if this is related, but I have recently been trying self-hypnosis as a coping skill. I found that I am pretty susceptible to its effects, and I worry that maybe I have accidentally caused myself to enter an altered state of consciousness. I have also been struggling inside for the past couple of months because my favorite narrow, intense interest (a symptom of AS) has been coming to an end and no amount of advice from any of my loved ones has been able to console me. (That's the reason why I started trying self-hypnosis in the first place.)

I know there are a lot of factors at play here, but does anyone have even the slightest idea of what could be causing me to feel this way? I don't see my psychiatrist for another month and I'd like to have some kind of idea of what might be going on, especially since my mom is worried about me.

Please don't wait for your psychiatrist's appointment, but speak to your doctor straight away. Unfortunately, no one here can diagnose you, and your doctor would be the best person to see.

I suggest going to a doctor right away.
