Trying to hint to my mum there might be something wrong with me.?

Well, since i was little i've heard voices and see the only thing i can describe as 'shadow people'. i've always beleived this to be real people and stuff.. but then i tried telling people an they though it was weird, i looked up all the symptoms if there was something wrong, and it looked like what seemed normal doesnt! i tried to say to my mum and she said: 'it seems like you want to have something wrong with you.' really angrily and stormed out. i cant talk to her with out thinking im attention seeking. she laughed when i told her about the shadow people.
