What’s the point?

I don’t see the point of trying anymore. I’ve been suffering from some form of depression and anxiety since high school and that was seven years ago. And nothing seems to have helped/gotten better. The past year and a half especially has been a struggle. I’ve been in and out of the hospital for suicidal ideation, self harm, and failed attempts. When am I going to get a reprieve from these dark thoughts? I’m tired of wanting to kill myself.
