I feel empty... help?

im just so fed up with life right now, fed up of my "friends" fed up of my home and where I live, where I work, my life as a whole im just fed up with.. I can never ever be bothered to do anything anymore, i'd rather just sit at home and do my own thing without people pestering me to go out.. I have come to terms with things like who I began to turn into. (mini regina george or 'mean girl') and i've come to terms with the fact I just cannot stand fake people and i KNOW my friends talk about me behind my back but whatever.. anyway that isnt even the point because i can't even be bothered to care about that anymore.. is this normal to feel this way? I'm 17 and i just feel like not getting up in the morning and I cant help but be negative with everything even though I feel like I have to put a postitive view on things :(
