When to throw in the towel

I will be keeping my thoughts here. No one looks here. This is free and I can be alone here. 

I'm 51. I have no friends. I'm partially disabled. I have no job. No relationship. And I'm sick with numerous diseases. Not a person has texted me or reached out to see if I'm alive.

I wonder why would I continue? No one would notice if I left. I've tried love. A dozen times. Failed them all. Tried jobs. Failed them all. No kids, nothing. 

The world doesn't need me anymore and I kinda wonder if I need it. 

I've heard that those without children will not get to come back to the earth. Maybe that's ok. I never felt at home here anyway. So maybe we should rip the band-aid off.

Something has to change, I can't breathe anymore.
