what am i?

im having big problems.
i dont know what i am! i dont know what do i really want i dont know what am i living for
i dont know what im thinking, i dont know which feelings are true. my brain plays tricks on me. shit. my interest changes by seconds. what i did is "WOAHHH this shoe is nice, ehh? ugly lor if see long liao"
i thought my friends dont even know my true personality since i have slightly multiple personalities disoder, but i myself dont even know me well too!this is kiap right?
sometimes i hypnotize my self YEAH I LOVE THIS YEAH I LOVE THIS and so i love "this"
but its not what i really love! its just im persuading myself to lie on my own? oh goddd im neurotic, i dont know what im saying.can somebody help me?
im having sleeping problems nowadays, whenever i close my eyes i felt like the world is spinning, its just so suffering until i lost my time on sleep.oh yeah. and i recently found that its hard for me to have a decision you know, A FINAL DECISION, i hesitated when i was deciding,it keeps repeating.
