help please

i’ve been struggling since november. i feel like i’m in a bottomless pit of sadness, it always comes to me i can’t NEVER CONTROL WHEN IT COMES. when i feel so terribly sad i can’t move my body is so sore and i feel so weak. i’m in high school and i ABSOLUTELY HATE THIS GENERATION ITS TERRIBLE. i can’t run away from it i’m stuck here in this shitty world full of shitty people. i don’t know what to do i have this feeling right now of sadness so i’d thought i’d share how i feel and if anyone has felt like this....
