I feel like I'm asking too much of others

I'm just trying to find the right words to express a thought. Not exactly sure what I'm trying to say, but I feel a bit like asking others to help me meet my needs is asking too much of them. Needs like hugs, or intimacy, or affection - things which I do need others for. But I can't ask for these things as even the most basic thing seems too much, like it requires a closeness I do not share with anyone despite my best efforts. I'm pretty sure any closeness I feel is not reciprocated, and my friendships are heavily one-sided.

I think I need to figure out a way to live without having these needs fulfilled. I know it's something I've managed in the past.
