I think I need help

hi this is my first post and I need help or opinions of other people I don't know.

I'm 17(F) lately I've been feeling like I need to get checked up. because lately Ive been more irritated towards everyone in my family whenever they ask me a simple question or joke around with me. j don't know how to describe it but my voice gets loud and kinda angry I don't mean it intentionally and I don't know why I'm angry.. I don't come from a abusive household to feel this angry, I ask my father if I should get checked up for something, because I don't feel like normal, I feel like something's wrong with me but he told me it's just me having a bad attitude..maybe it is but Im not sure I want to get checked or diagnosed but I feel like I'm making it bigger then it is..

I don't know what to do
