I went through it living with my mom and long after I left home, got married etc. She was a very negative person and seldom laughed. I found out that her childhood and early adult life were very unhappy (her dad, my grandfather, verbally/physically abused them too and ultimately abandoned them). Unfortunately I found out much later in life…if she had shared that with me we could have maybe understood each other and started to build a real relationship. As it was, I left home as soon as possible and her negativity followed me in everything I did. I had very low self esteem and only through other friendships/relationships did I find out that I wasn’t everything that she told me I was, that I was a worthy person with talents and abilities and that everything I did WASN’T full of flaws. You must find a way to keep telling yourself that you are a good person with good qualities and most of all that you are worth loving. That was a long journey for me.
