Am i schizophrenic (please help)?

i'm 16 and a girl my dad walked out on us when i was real little. i started smokin weed, drinkin and poppin pills at about 12-13 yrs old. i've recently started taklin to guy celebs i see on tv (almost like dad figures), over a course of a yr and a 1/2 i've seen the wayans bros, leo dicaprio, and now its johnny from jackass. the screwy part is that i see them come out of the tv and they follow me and walk with me wherever i go. please no mean comments im pretty freaked out cuz i really think i know them. ps, i hate staying in one spot, im always wandering off from wherever i am, even at school.
