I haven't slept all night

I can't remember anything that's been happening. I can't even remember that past couple of days. My eyes have been acting up, I've been sleeping more than usual. And this song just came on:

And it's killing me... I miss her, getting a GF will destroy your heart once she leaves you...

Something is deeply wrong with me, I can't remember anything, one night I get cross faded while sleep deprived, now my memory is total shit, I can still talk normally and everything, but I just can't remember anything that's been happening for the last few days...

Tell me i'm going to be okay, that I'll be fine, even if that isn't that case, please just tell me it'll be okay

I'm cold, it's dark here, I'm lonely...
