For those taking Sertraline for anxiety, what mg was your sweet spot?

I'm 48m. I suffered from anxiety in 2020 (who here didn't), was prescribed Lexapro that made me depressed, so got off it. Then in 2022 had so much anxiety that led to depression and was prescribed 50mg Sertraline (Zoloft). Suffered major mental side effects, but was depressed already so i couldn't tell the difference. After 2 weeks and some circumstances in my life that improved, I was feeling better. Been on 50mg Sertraline ever since. When I think life is all good, I slowly try to taper off, but anxiety sneaks back in. Recently suffering major anxiety and panic attacks and my psych told me to increase the dose so I increased by 25mg. 2 weeks, still suffering. So on my way to 100mg. I've heard 50mg is actually relatively low. But nervous on going higher. So wondering what's average? Where was your sweet spot? Was it just the change in circumstances that helped me earlier? Or am I just taking a dose that's actually considerably low? Or should this be working, but I'm just on the wrong stuff?
