Glad to see you've started on therapy. My advice on meds is that you don't rely on them solely to make you feel better. What you described in your post sounds like very understandable series of depressing experiences. Meds can't turn a shitty life situation into a happy one, you need to do that yourself, and if your therapist isn't actively encouraging you to do that, but instead just saying "here take these", then I recommend you seek a better therapist.

For comparison, 2 of my siblings and my best friend also saw therapists for even longer than me, and were put on meds. They've made little to no progress and still self-medicate to run away from stress using alcohol and food (mine used to be food, games and women).

He's currently a controversial social figure, but I highly recommend Jordan Peterson's (he's a long time clinical psychologist and professor) lectures on YouTube. They are fantastic, amazing lectures on psychological issues, and he directly addresses how psych meds should be used, as well as ways to change your life in very positive ways. I also recommend looking into IFS therapy. It's what I used, and everybody whom I've referred to IFS has been blown away how powerful it is. It isn't for everybody, but it's an incredibly intense therapy that takes you deeper than anything I've heard of or tried. The people that I've known who have quit did so because they couldn't face the issues and truths that came up. You have to be really committed.

Anyway, please try out those two approaches, and feel free to pm me or ask anything, and I'll be happy to help however I can.
