@Damage some people are just hard to have relationships with, and that includes parents. Even if your mother were totally average and normal (whatever that means), you might still have a hard time with her. Parents aren't any easier to get along with just because you've known them for longer; it's okay to find that relationship stressful, the same as any other. I have kinda the same problem, and my mom is pretty ordinary.
@Damage I feel like it’s particularly hard to have a strained relationship with one’s mother. Of all the relationships you’re told must succeed at all costs, it’s that one, and it’s really not true. It’s great when it does, but it’s as arbitrary as any other connection between two people.
