very anxious

Girls, I need some help. I'm struggling really bad with anxiety. I'm 8w2d today. I have an anxiety problem anyway, but it seems in the last few weeks things have been exacerbated really badly. I have been taking Buspar for anxiety related issues for about 8 months (class B, safe during pregnancy) but I cannot shake this overwhelming sense of tension and anxiety. I am constantly worried about miscarrying even though I know that if it's going to happen, I have no control over it.  I know it's futile to worry and I know that I have to stop stressing but if you've ever experienced anxiety attacks before, it's hardly something I can control :( Can any one offer any sort of words of wisdom or advice on how to get through the next few weeks? I know I'll feel better after the first trimester.  Any suggestions on ways to reduce the anxiety? Any help is greatly appreciated :(
