I don't understand this about myself...?

My mother's behavior was quite erratic when I was growing up. I have several theories, first she may be going through menopause which does make older women go through mood (sometimes extreme) swings. The second theory is a bit tougher to deal with, she may have some psychological issues. She may have unresolved trauma(s) from her life. Whatever the reasons for HER behavior the only thing YOU are responsible for is your reaction to said behavior. My advice is exercise and take the best care of yourself you possibly can. You cannot do anything other than call the person on their behavior and quietly walk away. Do not respond with anger, it never works and for god's sake man don't wallow in self-pity. It is the most dangerous of paths, addiction, suicide...etc. Be strong and think logically, emotions need to be measured. Think deeply about your mother and perhaps you will understand her and eventually you.
