What's the best way to deal with a mother that overreacts about EVERYTHING?

There could be many reasons for her outbursts and anger. Even though she may be dealing with her underlying issues in the wrong way, she may be going through menopause which can be horrible for some women as it really affects our hormone system. She also may be having issues with the man in her life. Aging also brings on mental issues and/or she may be in depression. You are getting older and will be leaving home soon. As a Mother, it is very difficult to go through the " Empty Nest " syndrome. Do something very different and ask her out for coffee, or to a juice stand or even for a walk in the park. Then lightly bring up how you feel being a young woman and that you have been worried about her lately. Try to get her to open up her feelings -YES-let her talk about herself. You never know-but life pulls hard punches and we never know when we may lose someone we love. Take it easy with her and let her know you love her very much !
