It's probable your own "issues" grew out of and continue to be nurtured by a less-than-functional environment involving the whole family. You might even be what family therapists call an identified patient (problems are rooted in a family system, but the "identified patient" is the only one singled out or scapegoated by the family members as having "the problem").

Ideally - though it may not be practical or possible - putting some physical distance between you and an environment setting you up to fail would be desirable. If physical distance is not possible, erecting stronger psychological boundaries may be necessary.
