Anxiety is perfectly normal in early sobriety Penny, at least it was for me and lots of other people here.
I think it's natural - all of a sudden we have all these feelings and nothing to numb them with. Then there's the physical ramifications of a body repairing itself to consider as well.
Seeing your doctor or exploring therapy can help if the anxiety is too crippling. Have you ever thought about getting that PTSD self diagnosis verified?
I've always been very anxious - and still am in many ways - but the heightened kind of anxiety of early recovery settled down for me after a few weeks or so
