My mother absolutely disgusts me.
What makes you so disgusted with her?
I feel like my mother is all about herself and she doesn't care about me.
If you're not happy with how your mom is treating you, just talk to her. She's your mom so I bet she'll understand.
I've tried several times but she is vague and ignores the issue at hand. You're right though and I will try again.
It can't hurt to try and perhaps this time you can use a different approach. Talk to her in a way that can't be responded to in vague terms. Be direct and assert yourself and how you feel.
