what is wrong with me?

I am starting wonder is I have some sort of personality disorder?  I don't like to interact with people.  I avoid it.  I would rather do solitary activities, whenever I get a new hobby I just focus on it and nothing else, like I am obsessed.  I get agitated when people are around me.  I started taking paxil about a month ago, it seemed to help at first, now I am having these weird nervous system sensations.  I also have been having night terrors, in the day time I stitch and have tremors.

I recommend that you find a psychiatrist, psychologist, or behavioral therapist that works well with you. I can’t give you a diagnosis over a message board, but, it sounds like you are experiencing problems that are absolutely interfering with your quality of life. Whether you receive a particular diagnosis or not, these are problems that should be addressed. I’m not sure who prescribed the Paxil, but medication of that sort should be overseen by a psychiatrist and this person should be hearing your concerns and addressing them. If he or she isn’t, by all means, seek out a different psychiatrist. The problems that you describe are serious and you should be actively seeking treatment.
