Yeah I've taken them before and basically you can just expect your mood to go up 1-3 points out of 10 on them. So you sort of stop caring as much about the things that are getting you down and can enjoy the things you used to like more. It reduces rumination on negative things, and helps you become more productive.
It's kind of like how we've probably all known some short ugly ethnic who seems happy 24/7 despite their situation because they never think about it too much. It just makes you a little more like that.
The longest I think I ever took one straight was 3-6 months or so because i have a naturally pretty upbeat mood but there have been times I've gone pretty dark and that got me through those times. If I didn't during those times I wouldn't have gotten out of bed but it kept me moving.
I'd strongly recommend you give it a shot. I mean, when I was 10 years old, all I needed to be happy was my Nintendo. Granted things change as we get older and we have different needs. But there isn't really any list of things written in stone we all truly "need". Just the list our biology drives us for and we assign on our own.
I'm not saying we don't want/need women on some instinctual level. We always will. But there are 60 million excess men in India/China at present who will all end up alone. So we're not unique in that. Men have survived living alone for millenia. I think we can still find ways to enjoy life regardless. Antidepressants have helped me at times when I was too low to even consider that. Can't hurt to try.
