Restarting a SSRI 7 years after it popped out

11 years ago I successfully used Lexapro for 4 years until it 'pooped out' on me (a few months after a switch to the generic version). I was then put on paroxetine which was successful at 15mg for 7 years until that just 'pooped out' on me (couldn't tolerate the side effects of a dose higher than 15mg). Have been on mirtazapine for the last couple my months and having an awful experience on it —my anxiety is so much worse. Physchiatrists next thought is to try lamotrigine (which he's had work with anxiety and depression before, but after this mirtazapine experience I'm terrified of trying something new. OR returning me to the Lexapro (which worked so well when it did) . I just want to know if it will work a second time around after poop out (which was 7 years ago) ? Anyone had luck with that?

You can only try, i have no experience with it unfortunately. (i have a box of lexapro that i havent started using yet)
