Existance can be bleak at times for sure. For things/issues/problems you can identify, perhaps there's also a little hope. Identifying what the thing nagging away at you is ultimately the first step in doing something about it - and we do have some agency in affecting our futures. We're not powerless against unfulfilled ambitions.
I hope my joke in another thread didnt land too harshly the other day btw and I don't want to sound all sanctimonious or preachy etc. But to me the scars of trauma and the realities of society/existance are often things we need to find a way to carry with us in some way, because we are powerless to change them - the futility of war for example, childhood trauma and so on. But you're worthy of love. You could absolutely find companionship. The bad bit is you have to keep putting yourself out there and as someone who struggles with self worth and with motivation at times I empathise with the things that ultimately lead to inaction. I find myself frozen at times over the most seemingly mundane of things, but the crippling anxeity is very real when it hits.
I don't know you or your circumstances, I have known friends to have crazily high expectations of perfect relationships and I don't know what the perfect companion is in your head, but lots of people are looking for companionship. If it's important to you, you'll find it, I reckon.
I always um and ahh about posting these in a doubting myself kind of way. All I'm really trying to convey is hang in there mate. Things can be less shit.
