It is sad that some people have such narrow minds that they need to have others fit into what they deem correct. You need to stop asking for her opinions and don't give into her need to tell you who you should be. Unfortunately some people are so insecure that they have a need to find ways to put others down. Often with siblings one sibling will have a need to find ways to put themselves above the others because they actually have more need for attention and approval. Your sister is a "bully", so just do your best to ignore her, bullies thrive on power and attention.
