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

Ive heard voices since I was 17... They started asking me questions then I felt like people knew the answers to these questions now I think how do people pick up on personal info like my passwords... I dont know if I'm being delusional and I'm just really that obvious but all I know is right now ive been hearing voices for approximately 21,900hours since it started when I was 17, I'm now 20.... The voices say I'm a waste of space... They ask questions... They put me in my place when I'm right so I end up being wrong.... Its basically me being bullied from the inside untill the outside world starts to bully me for being bullied by what they dont know is an unreachable source of knowledge that is attacking me... Its actually like my smarts is attacking me!... I wont let it be smarter... I do not know... I NEED this TO STOP
