It's good that you have a little perspective here. It can seem a bit funny when looking at the grand scheme of things that hairloss can affect some so terribly. But we're the centre of our own universes and regardless of whether someone else's issues are far more objectively worse than our own, its human nature for us to become obsessed and fixated on our own shortcomings.
I think it comes down to a few factors. Hairloss is so obvious, its pretty much impossible to hide past a certain point. People may well perceive you differently if you have extreme hairloss vs a full head of hair. Not that its right to do so but we've developed a knack for prejudgements and everyone does it.
It's not as attractive (for most men) so you knock yourself down a few pegs in the social/dating hierarchy. That's not an easy pill to swallow for some.
The way I see life is you've got to play the cards you've been dealt. I know I've been blessed with a life so many would kill for. I have my shortcomings, hairloss being one of them, but overall I'm pretty f*****g lucky to be me. I do what I can with hairloss, I take what needs to be taken and then I do my best to put it aside because I feel as though obsessing over it makes things one hundred times worse. Its mentally exhausting and not productive in any way shape or form. I've accepted that as long as I'm doing the absolute most I can do to preserve my hair (risking negatives up to the point I value my hair) I can't be upset or angry at life. And if I'm really not doing as much as I could be to prevent hairloss than I have no basis to talk about being unfortunate whatsoever.
But mainly, I invest in other areas of life. My work, my relationships, my health, philosophy, history, spirituality. There are so many fascinating endeavours in life I know I'm not gonna let myself get hung up over the small things.
