Now I feel embarrassed and feel like I may have shared too much. She was talking about her family in a similar way but mine was clearly quite a bit worse.
You know the fact that your story was worse might have made your friend feel better... .Things are bad but not that bad, Lexicat has it worse.
I would not be embarrassed that you shared with your friend it might have been scary for them to talk about their situation and you being able to identify with their story was probably validating.
Don't beat yourself up. In my opinion you can't go wrong if you are honest.
So I was married to an alcoholic for 20 years and my mom is very controlling, my SO has a recovering alcoholic mom and 2 brothers
and an uBPDxw, my best friend has a bulimic step-daughter and a brother who struggles with drugs and alcohol... .See... .Everyone has people in their lives with problems and issues no matter what people say no one has a "perfect" life, don't feel bad for sharing your story.
