i hate myself

i feel like i cant deal with my life anymore. i just cant. i feel empty if you know what i mean. i feel like i cant stop disappointing people around me. i feel like a complete disappointment and on the verge of tears all the time. self-harm was one way i dealt with it. its summer now and i cant cut myself without being noticeable. i dont know what to do. i feel stuck in my life and i hate myself.
