Of course ask for professional advice first. But in my personal experience one SSRI helped me through a tough part of puberty a bit, but also made me feel like I wasn't really living anymore; like I was in a bubble with all of the pain but also the real joy splatting up against it and dripping down. In my more recent bout of depression after trying numerous therapies I tried several SSRIs (along with therapy) but ended up worse off. Most side effects went away after a month or so, but years later I'm still not sleeping like I used to before taking them, but I've gotten used to that; it's not that bad. I feel like Americans think of them like some kind of miracle drug/candy which I'm pretty sure it isn't for most. From what I've read so far they haven't been able to scientifically prove effectiveness above placebo level. Still, if you're out of other options and with a therapist you feel good about to guide you then I'd give it a go. One way or another I wish you all the best! Remember we're all just pretending to know what we're doing while we're really just winging it and that's fine
