I don't have BP but my son does. As soon as he was diagnosed I read everything I could to try and help him. I think that your dad probably just has no idea how this effects your life. I have supported my son when he tried to make it without meds, (which did not work for him) and now I try to help him deal with the drugs he takes now. If you understand this illness, you know you can't shake this off or will yourself to get better. If those drugs help you at all, just keep taking them and your dad will see that you are getting better because of them.

Don't hate yourself. You did not do this.
Good Luck!!
