Confusion...

so i work a million hours a week just to get by.  at one point, i had been off work.  my therapist would not allow me to work.  my mom helped me so much, paid my rent, and that was abig thing because we both struggle so much.  she has almost lost her house, but somehow she came up with the money.  we came to an agreement that i would pay her at least $20 every pay and by the end of the year, whatever was not paid will be forgotten. 

 tomorrow is payday.  i have to pay rent and that leaves me with $40 to last me 2 weeks.  i told my mom i can't give her anything this pay.  her response was to not pay my rent so i can give her money.  i said no.  now i am being ignored.
