[Montie]

...relationship going downhill? Okay here's my story. I started talking back to her since I was 13. It was just stupid. Now, I'm turning 21 in two months. I can't even stop myself from doing those things. My mom is threatening to move out because of my rebellious and selfish attitude. ive been trying to make things work about not talking back to her, but I ended up making things worse. I hate myself for this. It might be too late to try to repair this relationship. I just can't even get myself to listen to her. I feel like I have failed her as a daughter. I just don't know what to do. When I got pregnant last year, I started to get along with my parents. Then, I had my daughter this past February. Six months after my daughter was born, I started talking back to her, yelling at her. She's been helping me with my daughter, and I can't even appreciate her. I feel so stupid. I just made my life a living hell. I've been apolozing over and over again and mom thinks that i'm insincere and I've been crying crocodile tears. I hate being this way.I'll just give up trying to make things work. Why try? I'm the worst, unappreciative, unthankful and insincere daughter that mom ever had. I just wish I had never been born. I'm such a screw-up. I'm such a failure who can't even appreciate her own freaking mother! I also don't want my daughter to treat me the same way when she grows up. I don't know what to do anymore. please help.
