this giant feeling of .. nothing.

outside i'm smiling, but on the inside i'm feeling empty. just .. empty. i'm never happy, i'mnever sad. i'm just really tired, all the time. it's almost like i couldn't have emotions, except for this giant feeling of .. nothing. i don't want to leave my bedroom, i don't want to get out and have fun. i just want to sleep .. forever. i don't unterstand what's going on with me. i think i need help, but i don't even know what's my problem in first place.
