I NEED to CEASE the VOICES in my HEAD!!!!!!?!?!? They are DRIVING me INSANELY ANGRY?

Since I was 17 ive heard things trying to ask me questions then people where knowing the answers to these questions... I do not know how in gods earth this is possible or even if I m so delusional right now that I cant remember.... I NEED this to STOP... they are saying I m a waste of space... They re saying I m victimised by everyone... They are saying people don t love me... They are saying bad things about people... They are driving me INSANE... I m being bullied from the inside untill the outside world is starting to bully me... ive prayed and prayed for the answer and nothing... Idgaf this is driving me up the wall and no one knows

I m 20 now
