Drug induced Anxiety disorder

I wasn't a real drug user....I used cocaine in summer 09' for the first time and again on Labor Day weekend...and then I went to a club....found a dude who said he had some real good stuff so I tried it & I bought it. I was using his stuff all that next Saturday....it felt really good. I was partying alone tripping out to my shows on TV. The next day I felt like something was REALLY wrong with me!.....everything was surreal and I did not feel like myself all day and was having panic attacks. I eventually went to the hospital that Sun night/Mon morning. They found cocaine in my system but they said it seems as it was cut w/something else. I eventually realized it was cut with probably Meth & PCP.....Idonno I went back to the hospital again a week later...they said I was gonna be fine. I am going through that weird always feeling high & anxiety stage right now a month later after use...I get tingling through my legs & arm & head sometimes. I be looking forward to sleep and I have been taking some pills that help w/ the Anxiety a lil, and sleep aides but as soon as I wake up and stand up the whole not myself high & anxiety feeling comes back feeling comes back. I be online all the time lately, searching for others that have been through this.... loneliness and depression also sets in trying not to think about death or watching anything too deep now. I was told I overloaded my brain and need time to get back to normal. I have a doc appt Tues w/ a Psychiatrist for the first time so that they can give me what I need to take I guess & talk. I hope I get some feedback.....
