I don't have huge issues with my parents, but my mom says a lot of things that bother me usually. T told me to remember that if something she says makes me emotional, it's okay to feel that emotion. It will go over in a bit, and that's all my mom can do, create an emotion that shortly after goes away again. He also said that I can of course say that I disagree and give my own opinion. But that she is entitled to have her own opinions as well, even if I don't agree. But it's important to not just get angry in her face or something like that. I can politely tell her or I can deal with my emotions on my own, I don't need to show everyone (not in situations where it's not called for, is what he meant, of course I can defend myself and all that).
