What I mean by this is, it is very important to communicate your needs and make your boundaries clear. You did mention you've tried it all, which leads me to believe that your mother is unwilling to listen. Sometimes people, for whatever reason, can't see past their own mental models for the world and are unable to extend empathy (yes, even to their own children). For your own mental health and well-being, as well as that of your daughter's, it might be best to limit contact. Or state clearly that communication will be limited if her behavior continues. You are in no way wrong for how you feel, it is a terrible feeling to be under a constant microscope. People may have good intentions with their advice, but they must understand that there is a distinction between care and micromanaging. One is sweet, while the latter is extremely harmful. It can foster mistrust in relationships, resentment, and can even lead to personal feelings of doubt, lack of self-assurance, and low self-esteem (i speak from exepereince). Constant degredation is extremely harmful for the mind; i am sorry that you are facing this difficult situation, but i hope you choose to do what will make you most happy and will be kinder for your heart.
