You are a very caring and supportive daughter. Your mum is fortunate to have you in her life. My daughters are all growing up and leaving home too. I've made my share of parenting mistakes and there are many things I would do differently if I could start over. Sometimes I feel hopelessly inadequate as a provider, a nurturer,a role model, and even as a person. My daughters are all such wonderful young women though, I know I must have done more right than wrong. Your mum has obviously done something right in raising you. I hope you will continue to support her, just please keep some healthy boundaries in place. You don't need to get sucked into her unhealthy ways of thinking.
