You are sensitive; life is going to pain you. Siblings can be especially capable of pushing our buttons. All I can suggest is try to find something else to absorb your attention. Bad feelings are best crowded out by competing stimuli.

If you can think of some witty way to verbally byeetch-slap your brother on these occasions, you'll likely find that enormously satisfying. If you're like me, though, you'll think of the clever retort a week later and past being any use.

Being sensitive has its upside. That's how it is. Any trait can be an asset or a liability, depending on the context. Try contenting yourself with the realization that your brother's tendencies will bring him what those tendencies deserve.
