I tryed em out about 3 years ago. It remains among the smartest things I've ever done for myself. The field has come a long way. I'm the same guy I always was, with lots less crushing anxiety.
If it's been a long time, give it another go. "I tried a cell phone in 2003 - it was shitty" sounds crazy. It's apples to oranges compared to what's available today. Turns out medicine is the same way sometimes.
Finding medication and a therapist that work for you is really hard. It can take a lot of work. But it's worth it. It won't fix everything, far from it, but it's worth it. Just keep taking it one day at a time.
You should try something like see a doctor and if that doesn't work try something else until it works and it can work and take a bit of time.
Give it another go. Worst case scenario is you waste some time and maybe have some side-effects.
I've had episodes in my life where I felt so trapped or constrained or ashamed that I thought about ending it.
I'm really glad I didn't. My thought process was broken. I would have devastated my loved-ones, and thrown away my life for deadlines / issues that no one cared about that much.
I have friends who have survived major depression and are mostly happy now.
There's hope!
