It sounds like your brother kind of sees you as a mother figure. Have you always had this type of relationship with your bother? One, where he could always come to you for help?

You do have every right to expect some distance from your brother. Listening to his troubles is very kind of you ~ but you always playing the same role, instead of him listening to your gripes at time, isn't fair. His snide, hurtful remarks about him being the healthy & successful one is pretty passive-aggressive.

It isn't easy to let remarks like that flow right over you, that's what you're going to have to try doing. Kids make remarks like that all of the time. It hurts, yes. But we can't give in to that behavior, because our giving in only reinforces their tendency.

Gentle hugs to you LaLuuz. I can understand how hard this must be for you. But the reality is that you've got a full plate yourself. The road needs to go both ways, otherwise there is no reward for you to continue the relationship. You deserve respect and sensitivity too!
