I broke away from an emotional abusive relationship and the worst thing is they make you doubt yourself, even when you are no longer with them. That negative seed of lack of self confidence continues to grow, like you are thinking maybe it is the menopause. It is not the menopause, it is HIM, he is the problem, not you, he is in the wrong, not you! It takes years of healing to fix yourself after being whittled down by an abusive partner. You are a strong woman, you were brave enough to move on, get him out of your life, do not let those seeds of doubt take root because then he has won, he is back in your mind, controlling your life again. I use mindfulness to help me live in the here and now, and focus on positives, deal with anxiety, it helped me move forward with my life. I wish you all the best for your future.
