I'm just a museum of failures

Need to get it off and admit everything I've messed up..i couldn't keep up my relationship, I got messed up, didn't have it in me what it takes to sustain a good relationship (having said that want to mention i didn't cheat though, i couldn't serve my partner in the best possible ways, felt we were misaligned) and impulsively left and now every single day my conscience is eating me alive and i believe nothing can happen of me. Even my academics went downhill, I scored horribly in my previous tests and did really bad..my parents are disappointed with me, we don't get along and in multiple occasions they have mentioned how I'm super unworthy. i have basically failed everyone including myself and everyday I can see my life crumbling down till it completely diminishes. it's all my fault, I am to be blamed for everything, i am so miserable and exasperated because of me and even atp I'm worsening. it's all me. I'm not deserving of a life and idk what Im doing here, I can never get anything right, idk what to even do anymore
