Have Sores On Legs, Picking At Face. Taking Antidepressants For Anxiety. What Is Wrong?

I am 58 years old. I have always picked at my face and ripped out ingrown toenails... which I created. Recently I have made sores on my legs from shaving my legs, some places the hair didn't grow out right and I couldn't stand it. I used a sewing needle to lift them up. In the last 10 months I have chewed my nails so short to keep from making my face worse, but I still have 6-10 places I can't seem to leave alone. I've been on several antidepressents since 1995 but my anxiety is increasing in the last 3 months. I'm going to a new psychiatrist tomorrow... I have not seen anyone for 3 years. I moved out of state for 1 and 1/2 years. Is it possible to get a combination of meds that won't make me feel dopey all day? I still have a life with my daughter, granddaughters, my mom and my church. I can't really tell my church friends... well, I don't want them to know. I guess I still want to hide the problem -- as well as the solution -- but by now, some are wondering what is wrong with me. My MD told me this has a name but I forgot it. I am also OCD in certain things and it tires me out. I don't know how to rest anymore. My question is mostly about medication results and will it really help? I think I just need to talk to someone on a regular basis. ALSO, I cannot afford to pay much. I am on disability for rheumatoid arthritis since 2002. I live in income based housing otherwise I would be living in my car.
