Misunderstandings can grow into resentment if the issues are not resolved over a long period of time. Usually, these arise from pain and unresolved feelings. Unfortunately, communication issues that remain uncommunicated can keep distance within families.
If you are determined to bridge the gap between you and your sibling, your best resource could be counseling. A licensed counselor can help both of you find that connection again and rebuild your family relationship.
A therapist can facilitate an environment that will allow all parties to express your feeling in a safe place. It is advised that you first talk to a therapist who can provide guidance on how to best approach your sibling about your desire to rebuild your relationship.
