How do I do it?  
Fear!
No choice!
Destiny!
Single parenting isn't for the meek.  It is not usually a choice.  I chose to stay single to do this work alone.  It has people misunderstanding me and plaquing me with "I don't know how you do it".  I didn't have a choice.  I feared what would happen if I didn't show up and show out.
I think it was always meant to be this way.  It didn't always come easy but it worked out for me.  Standing on the cliff of being almost done with this parenting gig is got me waxing poetic about life and next steps. So here we go again.  Fear of the end, no choice but to bend.  Destiny showing me how to do it.
