I've had increasing problems with symptoms rise up recently and I've been becoming more aware of mental illness and emotional abuse, I've had a pretty isolated life so I never really knew what was normal but the internet is helping me realize that I have problems. 

I can't focus, I have difficulty sleeping, wake up easily, recently I've even been having very mild hallucinations when I wake up like hearing noises in my head, but that's pretty rare. in the past my brother has yelled at me frequently and belittled me, I thought this was just him being an older brother due to my parents saying his bullying is just in my head but i now realize that it's abusive and effects my daily life. Whenever he yells at me I start shaking and my heart races and I think this may have caused many of the symptoms I have now. 

I've also always been pretty paranoid and sometimes skittish. In the past I've gotten very scared over almost nothing on a couple occasions but hopefully I'm over that now. It's probably also worth mentioning that I get chills whenever anyone touches me, even people I'm comfortable around like my parents, I think it's called haphtophobia.

Anyway, sorry to rant, I know I'm not the only one who needs help but since I don't feel comfortable asking my parents to see a doctor because I think they'd say that I don't need to, I thought I'd ask Reddit instead, any input would be appreciated, also in case it matters, I'm 17, and will be 18 very soon. I know age can affect mental illness. 

Thanks everyone.
