i’m going to kill myself after graduating high school

i’m 17 and i have no future. i’m not smart enough for school and i’m leaving with barely any qualifications. my mum won’t stop telling me about getting a job, no one will hire me. i want to kill myself so badly. everyday i fantasise about suicide.

i’ve felt this way forever, and i know it will never improve. i can’t picture myself happy. i don’t know how i’m going to kill myself, i have no access to firearms (i’m in the UK) and i know ill be too much of a coward to jump off a cliff, just like how i was too much of a coward to hang myself. i hate every aspect of myself.
