What should I do? Please help!?

Well im sorry to say this but thats kinda abusive what he did to u. u need to explain to him that u've changed. tell him ur not the same person u used to be. Tell him that u didnt mean it in that way. If u say something in a rude voice then thats well obviosly rude :P, but u need to work it out with him. figure out what ur depression is and if u no, just try to solve it. Some ppl in my family have deprssion because of other ppl in my family. And some of them try to fix it. Some of them are afraid. U need to reach out to ur dad. He probably doesnt understand that u changed.He probably still thinks of u as the girl that was rude(the past apperantly). Just reach out to him. Try to talk to him in a very calm way.
