Seven weeks pregnant and my mom is driving me crazy and stressing me out?

Honestly, you're right. It's none of her business what you do with yourself, and I think it's incredibly rude of her to tell you to have the baby aborted and to not tell the father. If she hasn't supported you financially, she has no right to tell you what you should do. Tell her to out, and if she really wants to be a good mother to you, she'll support you no matter what you do. Good luck.
