Long-Held Resentment Toward a Sibling

You still show up to the same family gatherings and trade polite greetings, but somewhere inside you an old scale keeps weighing: who got more, who was forgiven more easily, who was always the favorite.

You might notice

You compare how you’re treated to how they’re treated even in moments unrelated to the original conflict.
One specific incident from years ago replays in your mind in full detail, as if it happened yesterday.

What generally helps

Write down the actual original incident in specific detail instead of summarizing it with a vague phrase.
Before attempting any reconciliation, try an imagined dialogue or a letter you’ll never send first; much of the weight eases simply by being voiced.

Note: If what you’re describing is actual abuse from the sibling rather than parental favoritism, that falls outside this situation’s scope.

When to seek professional support

If this resentment is blocking family contact altogether, or surfaces as anger outbursts that surprise you, working with a mental health professional will help you process this more safely.
