I know how you feel. I'm tired of it too.
I wouldn't think that the Paxil would cause you feel that physically ill with such a small raise in dosage, but you should really check with your doctor.
Being shy makes it difficult to make friends, especially, along with the depression. I would definitely suggest counseling even though it makes you uncomfortable. If you are going to make friends you are going to have to go out of your comfort zone.
Best wishes and hope you feel better soon.
