I've dealt with the suicidal impulses feeling that things will "never work" .. and I also have extensive hair loss. (I was born in '68, so I am at about the same stage in life, and the hair just has disappeared.) That is one of the things that makes me very sad, because I'd love to have the freedom of "real hair." I don't think I can recover a normal head of hair by any currently known routine, and what I could recover probably would cost me far too much money that is best spent on other surgery.
Many of the hair systems out today seem to be excellent, though. They are about as close to "real hair" as you could get, you can wear them for a few months (in the shower, to swim, etc.) before replacing them or even taking them off, from what I understand. Yes, it will cost you.. but if it's important, then you find a way to pay for it. They also look very real, from what I've seen, since they are often made from human hair or a mix of human and synthetic.
Not to downplay any of the OPs feeling's -- goodness, no. Not having my own head of hair is one of the saddest disappointments of my life, I think. But again, it is just the hand I have been dealt. So either I let it be a roadblock, or I find a way to accept it and find happiness. Hair is ultimately just hair.
I usually am the most messed-up when I have to keep facing the people I'm hurting by pursuing this route, because I never wanted them to have to suffer for me to be happy. My darkest nights usually happen when I feel like someone gets hurt no matter what I do, and I don't see a way around it. But if you have got people who love you and support you and stick by you, well, the hair issue can be dealt with even if it's not the ideal outcome.
I hope you can research some alternatives and work through the crushing disappointment to see what positives you can still find in life regardless. There will be some things you cannot fix perfectly, but happiness is partly a commitment to finding it.
