You cannot blame yourself for your daughter's mental health issues. Unless abuse is involved you cannot make someone mentally ill. My brother and I are not very similiar in act or deeds. I have mirror image identical twins and they are nothing alike either.

As parents we are human and make mistakes as our own parents did. But as an adult you cannot continue to blame your behavior on mistakes you perceive that your parents make. You cannot take the blame for her short comings anymore than you could take the credit for her successes.
