It usually was people id seen recently like in movies, but as I grew older it became random and i even began creating random, strange characters I even felt like I knew where they were and Id look at them. Im 16 now and a few years ago I was diagnosed with depression and severe anxiety. I take lexapro for the anxiety but still feel as if im being watched 
Never told anyone this. 
Am I a schizophrenic or is my anxiety just insanely powerful?
