SSRI’s not working

I was on Zoloft for around 12-13 years. It worked amazing at first when I was a teenager. Over the years I’d have to up my dose cause my symptoms would return. I got to a point months ago where my symptoms returned heavily and I went to the max dose but no change. I tapered off and now I’ve tried Prozac which seemed to make symptoms worse and no I’m trying lexapro and I feel like the same thing is happening, symptoms getting worse. I’d love to hear others experience with medication and what helps.
