Should I give up on my Mum?

hiya, its sad that your mum treats you like this.i agree with your friends,move back to your dad's.talk to him about any think.he might find it hard for a few times you talk about personal stuff,but he is a man and he will know about these things as well as you mum does,so don't be scared to ask him any think,he is your dad and you should be able to talk to him over any think.even you being bi.good luck.x
