Very depressed

"There's a lot of other fish in the ocean"...but what if i fell for a shark thats already bitten out a large chunk of me and swam off? =( i dunno what to do...i'm so lost. So much is running through my head. i don't know what i'm supposed to do...i keep talking to myself in my head so much. i don't know who i am anymore...its do this or do that... i don't have a will for anything anymore. Lucky i'm scared of pain, otherwise i would let go of everything which is pretty tempting since it would mean the end of my sadness.
