do i have schizophrenia? what do u think is wrong ?

lately i have become very agitated all the time. i can't control my thoughts. i hear voices telling me to kill and harm people. they keep agruing in my head. i heard trees whispering at me. and i saw a creature coming after me. i feel very disconnected with the world. sometimes i get rages that i can't control , i try to pull out my skin and smash my heard against walls slap myself .. stuff like that. sometimes i feel like my mind is in a knot and it may affect my speech. i always think that hidden cameras are on walls . insects etc and very body i know is watching my very move .sometimes i talk to the insects , sending back messages to people watching me. voices and thoughts told me to kill my cat so i did it or at least try to.. it felt great . sorry! and other stuff .. i see these little bright light everywhere making me think am not on earth i know it's wise to see adocter but i will like to know now. what do u think is wrong with me.am i schizophrenic as many ppl say or is it normal?
