Why do all good things come to an end.

Why am i not being myself to myself nowadays?I feel used, i feel like i am a spare tyre, i feel helpless, i feel useless.Nobody understands me, and nobody will understand. Nobody.I need to live a life on my own, i'm alone now with nobody to guide me all along.I mean, not anymore. I'm sorry for all the things i've done.-.I can't finish my food for the past three days..I get a fever and refuse to eat panadol..I always think negatively of myself..I hate myself for who i am..I hurt others 24/7..I suck.
(life's a !#$%^&*&%$!)
