I don’t understand the point of relationships

I don’t get anything from knowing people. They don’t get anything from knowing me. So we’re all just sitting here stuck together. Doing fucking nothing. I’d rather be alone than waste time with other people that are clearly unhappy and bored. I have nothing to offer other people. Why can’t they just let me be alone. I don’t date because I can’t be a good partner. I don’t want friendships because I can’t be a good friend. I don’t understand why people won’t let me be alone. I’m not good for anyone. I hate it.
