I struggle with this too. The small amount of joy or interest that I feel is not worth the stress and pain of living in the human condition.
I am also very lonely.
But, I have a philosophy degree! I can think deep, deep thoughts about the existential despair that clouds my mind. I’m thinking that there really is no point. Logically, if I know what the point of life is, then I’ll eventually be asking what’s the point of that thing?
The chain of purpose has to end somewhere with the ultimate “point,” that everything is building up to. And that thing would necessarily have no point, but it is okay because it’s somehow a point in itself. Maybe life itself is the ultimate point.
And that can be a good thing, or at least not a problem. I’m paraphrasing Alan Watts here, and he has a talk about how there is no point, just like a dance has no obvious point; it is definitely not an endeavor to reach a certain point on the floor. Similar with music; the point of music (good music, anyway) is the music itself, and not just to get to the end of the symphony. There’s much more to sort out on this subject, but this is more or less where I am at right now. Connection is hardwired into us humans. We need others and the physical effects of loneliness are substantial. I’m buggered though, if I can tell you how to connect with others and not get hurt/taken advantage of/betrayed, though. That’s why I think so much, It’s a problem that may be impossible to solve.
