SEVERE seperation anxiety. I'm 22?

I'm 22, I was home-schooled and graduated with almost a perfect GPA by age 17. I have always been a mommas boy, even going to the extent of being very over protective of her. I lived with her up until 8 days ago when I moved cross country for my job. I have been having debilitating anxiety ever sense the day I left. So bad that I am considering quitting my job and moving back to PA. and back in with my mother. Never met my father and my older brother moved to the UK five years ago with his wife. I can take Xanax but I often become too sedated and have blacked out a few times. I have taken them legally for 4 years so it takes alot to calm me down, and more often then not they cause blackouts of memory problems for me. I have absolutely no problem at all quitting my job. I can easily get another back in PA. My question is, I have been like this for as long as I can remember and counseling never helped. Is it likely ill be like this my entire life?
