Still having anxiety. =(

I'm two weeks post-removal and was feeling some relief after 4 months of anxiety.So this weekend I felt alot better. But yesterday and today my anxiety level went from controlable to all out panick attacks! I fell like nobody believes me or understands what I'm going through. I work and go to school full time, but my stress level has never been this high and i have never had anxiety. I'm having crazy thoughts about death and anxiety about anxiety and I'm so mean! I snap at everything. Nothing makes sense in my mind and when I verbalize them to family and friends I feel even crazier! When will this end? I just want to back to normal with trying any meds, I'm already taking xanax for sleep and even that gives me anxiety! Reading everybodies postings makes me feel alittle better. But then I'm so worried about my recovery. My doctor even thinks that I am just stressed, but I know my body and this is not me.
Thank you guys for letting me vent, I'm sorry its so long.
