I am severely depressed and lonely in my battle with my mental health. I feel like no one can help me and no one understands how bad I'm doing. But the people I can lean on, are getting tired of hearing my problems so I've come to standstill. I don't know who to talk to anymore. I don't want to be a burden on anyone. so I just keep things to myself until I finally break and have a mental breakdown.
