Very nervous to start Zoloft

I have been trying to get healthy and I have terrible anxiety attacks whenever I check my blood pressure so the doctors through my Bp was through the roof when I reality it was probably lower. They put me on metoprolol which was supposed to help with anxiety but sent me into a tailspin of even more anxiety.

I stopped taking it after 5 days and my doctor agreed. I’m now stuck with constant fight or flight anxiety having to rock or move my legs to find relief. So doctor agreed that managing the anxiety was best for now so gave me Zoloft.

I’m really scared to try it because it seems any changes in my brain chemistry or body seem to make me worse and I can’t handle feeling any worse than this. Advice would be helpful.
