Paranoid

I guess the reason I don't tell my parents about anxiety or depression is because what if I'm wrong? What if I don't have either and I dragged them into something that doesn't exist? I know I have something, but is it really that? Or that bad? What if we go to some clinic and they have to pay money to get me checked out and it turns out I'm fine? Or what if I tell them and they just laugh me off (it's nearly happened before)? I don't know. Maybe I'm just paranoid. I just wish they would pick up on the clues I've been leaving.
