Just want to run away....I feel like my body is in a state of constant flight mode right now just want to run far far far away, and I don't even have a good reason other than feeling trapped and I shouldnt even feel trapped but I do....worst of all its too late to speak up and tell her shes smothering me that shes being overbearing that shes being a helicopter mom and that shes done too much....if she knew I felt like this Idk what she would do....
