I feel restless

Idk what the fuck to do rn i want to tell the guy i like that i like him but he's too popular for me and prob hates me and i feel like i wanna cut myself or hurt myself or run away from home witout telling my mom or my siblings or anyone at all and just throw my phone away and block everyone. Or just do something drastic. Cus i wanna tell my crush he's the only thing acc keeping me happy and going to school but he don't even care abt me and i want to go home so bad i want to run away back to the Faroe island's but i can't be there anymore cause i have to live i denmark for mental help, but i hate it and i can't feel happy here i js want to kms. I need a distraction or something i js needed to vent. I need to get these feelings out i want to scream them:/
