I'm going to berate my mother for not having a college degree
Why are you going to berate her?
She never finished school because of me, I feel like it's her fault my life is so miserable
If I understand you correctly, she ended schooling to take care of you and you're going to berate her for that? I don't understand the full story but that is messed up on your part and you should acknowledge the sacrifice she did for you. She's the reason that you're alive right now and I would recommend you help her so that she could help you get a better life.
You don't get it. I'm going to ruin her life one way or another.
I don't know why you resent your own mother who sacrificed her education and took care of you. If you can't help her in any way at least don't abuse her.
