My two year old has been living with my mother for the past year. I didn't have a stable place to live and needed one for my daughter's well being.

I mentioned to my mom this morning that I might bring my daughter back home with me, even though my fiance and I are still living with his parents. Ever since then she's been telling lies to my fiance's mom about my parenting. Saying things like I cried all night until I got on the internet. I cried for 10 minutes and it was because I was frustrated that it was hot as hell and i stood over a stove for 20 minutes cooking for 1 person. Instead of being treated as someone who was visiting, I got to my mom's and found out that there was a load of dirty laundry with clothes that had urine on them that my mom have "saved especially for me". She told more than just that lie, but at this point, I just don't know what to do.
