Need to vent

My mom is driving my insane. I'm a single mom with a 5 month old and live with my parents. My mom has always been very controlling of everything. She's constantly taking my baby from me and telling me what I can and can't do. Some recent examples: 1. I woke my baby up from her nap so I could feed her. I sat down with her and started feeding her with her bottle. My mom came over and grabbed my baby and the bottle because she wanted to feed her. 2. I finally got my baby back from her. She came back over and tried to take her a few minutes later. I told her "no" and she got offended and walked away. Came back again a few minutes later and took her without asking. 3. I told her it was time for my baby to take a nap, but she told me it wasn't. She's my baby and I know her nap schedule. Of course my baby got fussy a couple minutes later and I put her down due a nap a soon a my work meeting finished. 4. It's snowing where we live. I was supposed to have a parenting class tonight and was prepared to drive in the snow and have driven in worse conditions. As I was walking out to my car to put the carseat in and leave, my mom yelled at me and said I wasn't allowed to leave. Didn't ask where I was going. Didn't express concern, just anger. I yelled at her that there was no reason to be mad at me and I went back inside. Got everything put away that I was going to bring with me and got baby out of her carseat. My mom hasn't said a word to me since. Those are all just from today and only the instances that included my baby. There are many other instances of her being controlling that don't include my baby. She also refuses to help me unless it involves her holding my baby. She won't reheat leftovers for me or fill up a water cup. I will ask her to do something specific and she will just offer to hold the baby instead. It's really pissing me off.
