I feel like a bad person

I’m 21M and I live with my Mom and Brother. My Sister lives with my Dad some distance away.

Without wasting much time; I have a habit of seeing negative qualities in my family. Let me say for the record that I love them as a brother/son, but I feel like a polar opposite compared to them.

My sister in short terms is an ahole so ignoring her; my brother and dad are huge stresses

The way they live and the actions they do make it almost impossible for me to respect them. More so my brother, but I have my opinion on both. I’m constantly seeing things they do that make absolutely 0 sense, is extremely immature and it actually bad for them but if I ever bring one up it’s shot down.

I love my mom and have no problems with her.

I just can’t stop judging. Part of me starts to feel bad because when my feelings towards something start to show; I’m looked at like a villain, but the other 80% of me knows what they do isn’t ok at all.

Deep down I think I’m starting to understand that I need to get away. While that is sad it’s also a part of life, but my problem is feeling the need to help.

Am I supposed to just stop trying to help at some point?
