I have been suffering from depression for around 3+ years now. I'm failing all my classes and don't know what to do. My parents are hard-working people and I feel like a weight and a parasite, and they already see me as a disappointment. I've tried killing myself before but haven't been successful. I think I'll probably try again. This is probably my last resort to find help because I'm scared of telling my parents. Please help me anyone.
