Seth,
Hello and welcome to HealingWell. You have quite a complicated medical history and I noted that your medications (astelin - normally prescribed twice a day for allergies) and Atenlol along with Vistaril etc combined may be cuasing some of your problems. May I kindly recommend that you talk with your Dr. and sort out your medications using only what is prescribed and as directed. I cannot really tell from your post what medications you are currently using as prescribed.
Sometimes we become our own worst enemy when we start taking meds randomly out of desperation for relief of anxiety and end up causing more anxiety due to the mixing and the side effects of the drugs.
Also as this seems to be a sudden onset of sx it seems wise to check in with a medical professional.
I hope this helps you in some small way.
Kindly,
Kitt
