Feeling like a complete failure

I can't do anything right. The moment I start overthinking a certain task, it becomes painfully difficult. There's nothing meaningful about my life. I'm tired of performing everyday tasks like getting up, brushing my hair, eating, etc. just for the sake of doing it.

I went through pretty messed up stuff recently which has made me question everything. It was traumatic and probably destroyed all of my self-esteem, sense of purpose - basically anything good or positive about my life. And now I'm on a path of self-destruction. I go to therapy but it isn't doing anything for me. It's just another "thing to do." Everything I do I manage to fail at it. There's no point.

Just wanted to vent. I don't have any friends so posting this seems about the only option.
