My parents have never been diagnosed with a mental illness. Could i still have one?

[Ayla]

I really think i might have an anxiety disorder or maybe bipolar. I'm really not sure. All i know is that something is causing me to feel very overwhelmed with emotions. and i don't know how to handle them. I've never been good at expressing my feelings. Probably because i feel like every time i've tried, my emotions were downplayed as not being serious. I've always felt like everyone expects me to be perfect and have no pain. When i've tried to tell my friends about problems they brushed them aside saying i was lucky to have the "perfect family" When i'd talk to my mom she'd always answer everything with a simple spiritual "do this" approach, without listening to the feelings behind them. Because of this i'm actually afraid to talk to anyone; even a doctor. I'm afraid the doctor will say i'm over exaggerating. Or worse yet; maybe they're all right and i am exagerating. It's to the point where i actually want there to be something wrong with me. because that's the only way i can explain the pain i'm in. I've been cutting myself for a year and i want to stop before it gets worse. I just don't know what's wrong with me! Also, i was looking up diagnosis stuff and it said family history is important. I don't know of much. I know my dad was depressed for a couple of years and my mom was anorexic as a teen. Also, both grandfathers and my uncle have struggled with alcoholism. And my uncle is on anti-depressants. Are these things considered signs that my family has problems with mental illness? Or is this normal? If there is no family history of illness, could i still have an issue? Thanks for any help!!
