I need to get out of bed

I've lost an appointment with my therapist and the chance to spend time with my mum just because I wanted to stay in bed. I'm throwing my life away by sleeping so much and I'm desperate to change but I don't even know what to do with my life. Nothing seems like a good enough reason to get out of bed.

Maybe I've ruined everything too much and I should just kill myself. I feel like I'm not functional anymore.
