Struggling to find an antidepressant that works

I’m about a week and a half into trying Wellbutrin for my bipolar depression. I just got off Prozac to start this, I’ve tried another antidepressant awhile ago I forget the name of. As soon as I got off the prozac I started feeling better, I was in a deep depressive episode for months and I guess the prozac was making it worst. The first antidepressant I tried also made me really dangerously depressed. I know I haven’t tried that many antidepressants yet but here’s number 3 that just makes it worse. It’s spring so I probably won’t naturally get depressed again for a few months (I hope), so I guess for now I will just not be on an antidepressant but… when the depression comes back I’ll have to try more antidepressants. I know meds are a process and I’ve tried a bunch of different stuff since my diagnosis last year, I’ve found 2 that work well. But man… what if I can’t find an antidepressant that works, what if it takes years? How long can I hold out when I get so depressed? I get depression really bad, I’ve never been fully manic. I’m just so worried and frustrated about antidepressants because I don’t know how long it will take to find something that works. They’ve all just made it worse so far.
