Topamax and overwhelming sense

My doctor put me on Topamax for migraines, but I can not handle the effects. I just started the 75 mg dose just as I was moving into a new college apartment with new roommates, and I felt like I was going crazy! I couldn't eat anything without feeling completely ill, I was spacing out, and I couldn't remember words.. for three whole days I couldn't remember the word 'tapestry.' I finally had to look it up in the dictionary.. not a good sign for a college student. The worst, though, was the overwhelming sense of panic that was getting worse by the day. I was no longer myself! The last straw was a panic attack, complete with hypernentilating. I have never felt so scared in my life. I actually had to go the ER to get something to calm myself down.

So, I decided to stop taking it. My parents talked to my pharmacist, and she told them that Topamax IS the type of drug you can stop "cold turkey." But after a week, I feel almost as bad as I did when I was on the drug! I still can't eat anything. Also, I wake up hours before my alarm goes off, completely sick at my stomach. I feel panicky and nervous. I have several bouts of diarrhea and this morning I almost didn't make it. I share a bathroom with three (normal!) girls, and it is getting to be embarrasing and annoying. Please, can anyone tell me.. when do the side effects go away?? I want to be a normal 19 year old again!
