my mother-in-law drives my absolutely crazy!

I never get a break because of no one wanting to watch my special needs daughter (they will watch my other two but nobody will take her) and I feel like I am nearing my breaking point. I just want an hour with my husband without the spawns but I feel like that will never happen so I cry a lot

i can't stop crying. i try so hard but am reminded over and over that i'm not enough and never will be.
