antidepressants?

I've been feeling extremely depressed lately. and I think it just has to do with the fact everyone my age are having kids and getting married and I've been trying to convince for 3 years now and no luck at all. idk I just also feel like at my age I'm not doing anything with my life. I'm currently 22 and I'm in school for nursing, only one more year left. but it just feels like everything is at a standstill until I finish school. dealing with school it's been hard to find friends and travel and enjoy life as everyone around me are. I've talked to a counselor and was thinking about getting on antidepressants, if you took any may you please share your experience of using them with me
