Welcome to HW!
Yup i been there. Just one day my anxiety was just full blown nuts (depression followed). I always had some anxiety but recently it just went haywire. Anyway, stick with the meds, they do take a little while to really get you going ( MIN 3-4 weeks), took me more like 8 to really feel all the effects. Might help to get into talk therapy, one of the best things i haev ever done. Hope you fel better
