2 months in and i want a day off

it's been 2 months and for the first time i really want a day off. not just a few hours, a day. a day that i don't have to think about anything that has to do with caregiving. where i can have my old life back. i know i signed up for this. she is my mom. it's only been 62 days with out a day off. but i want one. i'm selfish. i have been sick for a week. from dec 24th to even today i don't feel 100%. i don't know what it was, but it kicked my butt.
