You are strong. To help people with their problems is no easy feat, but you also need support. I totally understand that. I feel the same way myself except nobody wants to talk to me anymore. You can definitely find support on here, even though it might not be a physical person, and there are caring people here. Have you ever considered seeing the school counselor if you have one or a therapist? I've been seeing the counselor at my college for almost a year now. It's free but it helps.
