And my apologies if this gets long and boring.
I am a male human in late thirties and I have been interested in the opposite sex for a long time. I am not ashamed of my sexuality now, or so I think. And I have as long as I remember wanted intimacy - which is different from just-sex - with another human. And perhaps because of my interest in the opposite sex, I have been seeking intimacy with a female human. I am not ashamed of this, either.
However, to cut the long story short, I have often been rejected, sometimes with humiliation, and left alone. Three times, people showed interest in me or even in starting a relationship, but they ended up humiliating and ripping me off in a few months of hanging. There was one exception: a good relationship happened, but that was geographically impossible after 6 months (we are in different continents now).
I have had sex once, but that was with one of the rip-offs. Still, that is not why I am depressed.
I feel lonely. And I seem to be unable to break the loneliness cycle. Luckily I am somewhat humorous and can sometimes make myself laugh. Some other times I manage to give myself hope. But the depression sucks it all up quickly, and if I manage to give myself an energy boost I will just climb up to ground zero again. I am repeating myself.
Contrary to sexual frustration, which my body sometimes experiences as kind of a pile-up of energy, depression and hopelessness weaken my body, to the extent that I sometimes find it hard to walk.
The worst part is seeing that I can't find someone who doesn't humiliate me but likes me, and it is increasingly less likely to happen now that I am closer to 50 than to 20. It feels like a prison. Hopelessness is more depressing than loneliness itself.
I recently had a serious negotiation with my worst self-destructive thoughts and we agreed to let me live

But I will try to stand up again. The hopeless and depressed me definitely has no chance, and has to change. I like the person I was fifteen years ago: fond of life. Now I have settled in a new country. Maybe the new society will be interested in the old me. I will try.
Thank you for reading.
