My mom and Grammy don't get along to well and mom goes into a rage at least once every day and screams at everyone and breaks things in the house. Grammy needs help with everything, going to the bathroom, making and eating her food, getting dressed, Everything! I can help with the bathroom and dressing and eating, but I don't really cook well and can't drive to take her places. Me and my mom get into arguments over what to do with Grammy. Mom is going home for a week so I will be alone with Grammy, we have some friends that will help while mom's gone, but when she gets back we will all still be fighting and unhappy. I don't know what to do because I want a break, but I'm scared to leave Grammy alone with my mom for fear of her breaking down and leaving for good, and Grammy refuses to leave the house to go to a care facility, even for just 5 days to give us a break. Please, I don't know if I should just stick it out for however long Grammy has left or if I can trust my mom alone with her or if I should just give up and get on with my life. Also my mom is a recovering alcoholic and the stress of this is making her drink again and she gets violent when she drinks.
