Wanting more friends but not having the motivation to meet new people is the worst.
I have a similar problem... I want to make more friends and actually do have the motivation to meet new people, but I also have a certain level of anxiety that prevents me from being truly close with my friends and any potential future friends I may get, for fear that I'd either be too clingy or would just bore them with stuff like history, or space, or mapping, or memes, or that sorta shit.
A girlfriend would be nice too but I can't see that ever happening.
I don't know how old are you and nobody, not even yourself, knows how close to or far from the point of your death you are, but I'm willing to make the guess that it's still far too early to say it won't ever happen.
