Skin Itching & Psychiatry. This.

Itching all over my body for last 3 years, the scratched area becomes like a mark & inflates for up-to 1 hour then disappear. Itching would be Very aggressive sometimes, making me to scratch over & over at a particular part. But for last 6 months there is no bumps appearing while scratch, but itching still continues. I remember the itching was disappeared inbetween for some months during last 3 years, I don't know how. But presently am suffering from that. Recently I visited a homeopath doctor and was diagnosed the problem as "Urticaria" and was taking medicines from him past 6 days but no improvement, I think he has given medicine for my anxiety disorder too (for which I am taking allopathy psychiatric medicine for last 12 years) But his pills make me too sleepy and tired during mornings. Also fear that I may face another panic attack as per present condition & medication like Homeopathy & Allopathy together. Pls suggest me, the best possible way of treating this. Thanks & Regards.
