Not asking for a vote, maybe advice, or just sympathy because I'm feeling bitter.
Background: My sibling lived overseas for quite a long time, coming back to visit occasionally, but not often. I get on well with sibling but we've never been close so to be honest I didn't miss them but my parents really did miss them. During this time my parents aged and I became a carer for them alongside working full time, and I resented the lack of support with caring for parents.
Circumstances changed, sibling moved back and also lived near parents for a couple of years, which has been great for all of us.
Today, sibling announced they have a new job overseas and will be moving away again. I'm devastated in part because I'm left being the sole carer again, but also because this time they are moving to the country that I always dreamt of going to, they are living my dream. I should feel happy for them but instead I'm so bitter.
