my mother has always been hyper critical of all of us but has recently taken this to new levels!She talks to me and my younger sister like we are dirt basically unless it suits her otherwise.We cannot understand this as we are happy in our lives with lovely partners etc etc but nothing we do is ever good enough this has gone on for over 30 years and while we are fairly loyal to her regardless she doesnt treat us with any respect at all.Suffice to satI am truly considering telling her to off!Any advice?
