Mums! - advice asap plz plz plz!?

She is just trying to keep you from making mistakes, being used, or getting into trouble. She does that because she loves you. She is probably jumping on you a lot, and being extra strict because of the way your brother is acting. She is worried about your brother, trying to make sure you don't end up in the same situation, and all of this puts a lot of stress on her. Give her a break. Believe it or not, she will end up being your best friend when you get older. My mom was the same, and when I got older, I realized how much she loved me. The other kids that had parents that were unconcerned, ended up in bad situations. I was lucky enough to stay out of trouble and became a success story.
