I am a person that definitely has some sort of trauma bcs the environment I grew up was shit but for the past 2 years I have experienced things that rang a bell in me and I think I might need profesional help. I am a 18F, my parents won't accept that I might have a problem so they refuse to get me help, so whatever I decide to do, I'll do it on my own and pay for it on my own. The question is, judging from the paragraph below, what do you think? Should I book an appointment with a psychiatrist or psychologist? 

Reasons I think sth is wrong with me: traumas, I have problems concentrating, intense mood swings I can't control that seem to change hourly these weeks, I can't control my anger, I am emotionally detached from everyone, I am suicidal and feel burned out.

Tips regarding the very first appointment with a mental health professional are welcome!
