The following is part of the conclusion on relationship problems with sister
Here are some suggestions on how to solve conflicts between you and your sister:
Talk to each other about what's going on. This may seem obvious, but it's important to actually have a conversation about the conflict, rather than just bottling up your feelings. Explain to your sister how you're feeling and why you're upset. Listen to her side of the story as well.
Be respectful and understanding. Even if you don't agree with your sister, it's important to be respectful of her feelings. Avoid name-calling, insults, and other forms of aggression.
Focus on the problem, not the person. It's easy to get caught up in personal attacks during a conflict. But it's important to remember that the goal is to solve the problem, not to hurt each other.
Be willing to compromise. It's unlikely that either of you will get everything you want. Be willing to compromise and find a solution that works for both of you.
Seek help if needed. If you're unable to resolve the conflict on your own, you may want to seek help from a therapist or mediator.
