How would you deal with an emotionally abusive parent?

You will be heading off to college in two years. So I think you should simply learn to endure it. You're not going to be around your mom all your life. She obviously has some problems on her own that she needs to work out. Sometimes people like to cut other people down because they see them doing better than they are. Your mother knows you're smart and that you will make something of yourself. Let her continue to bring you down, it's only hurting her in the long run and it's making you a stronger person
