Am I suffering through depression? Now.

I can't sleep much and I have lost interest in everything I loved. I spend most of my time locked away in my room and I barely know what's going around me. I hate going to school and I feel tired all day. I don't like socialising and I cry over every small thing. I am frustrated and I feel suicidal and life seems like a burden. I can't consult a psychiatrist because then my parents will know and I can't ever let that happen. I have self harmed so many times I can't count. I cry myself to sleepy EVERYDAY. I can't express what's going on with me to anyone but I just can't bring myself to be happy. I don't know for real if I am depressed and I would really like to know though a part of me knows I am going through severe depression but I tried to not come to terms with it but I wanna know for sure now.
