Hi Eileen and welcome to OCF.
Treatment is scary...no doubt. Try to stay calm as much as you can and like Eric said...talk to your doc about what you are feeling. There are many patients that have taken something for anxiety, myself included. Don't be shy...ask for what you need.
I can promise you this....you will find the kindest people in the world on this site and we will support you through your journey. Hang in there and I look forward to seeing more posts from you.
