This was my experience too. Tried countless antidepressants starting in middle school. SSRIs/SNRIs never really worked, as an adult they would actually trigger manic episodes (which I misinterpreted as fixing my depression because I was productive and felt great). I had a manic episode after a vacation (turns out that messing up your sleep schedule from jet lag can trigger them) and finally decided to get help. Lamictal was a night and day difference for me. Wish I'd figured it out sooner but it's hard to recognize when you mostly just see the anxiety and depression.
