I am a 41 yo woman diagnosed years ago w/Hypothyroid for which I take Synthroid daily. However, before each menstraul cycle, I become aggitated, I scream and rage against my children and husband. I mean absolutely no patience and I am talking about blind rage. I cry, feel depressed and say the most horrible things. Now, my husband wants a divorce and I cannot blame him. When I am in these cycles, everything feels hopeless. When I start my cycle, everything calms down and I look back either surprised by my behavior or like an alcoholic during a black-out (I am not a drinker). I cannot e ven remember how or why things spiraled like they did. I push people away and w/draw. I have an Endo who treats the thyroid but I do not know if I am pre-menopausal, if it is my thyroid or if I am experiencing mental issues. Whenever I have addressed my anger feelings w/my OB, he blames my thyroid. When I discuss it w/my Endo, he adjusts my Synthroid. I should add that my menstraul cycles are not even that bad or painful. What is this and who can diagnose it?
