I believe I am being unreasonable but what I really need is for people to pull me back out of massive pity-party that's spiralling in my brain.
I'm an older sibling - we're both married, employed, doing well. Both living abroad, sibling is physically closer to where parents are. Parents divorced when we were in our 20s, both now alone, elderly and ailing, living in our native country on pensions that are not sufficient to survive (or even pay for their medical needs). I've been supporting them financially since I left home (15y ago). I earn enough to do this and my family doesn't go without because of this. Since sibling got a stable job, they started participating this support. The idea was 50-50, but in reality its more like 70-30 (I cover 70). This also is fine because I earn more.
However, my sibling is rarely paying on time and I often have to remind them to do so. Parents are, of course, not aware of this because I handle all transfers from my account - so even if sibling doesn't send, I still do.
Furthermore, sibling sometimes goes weeks without even sending either parent even a text message. This results in parents being hurt and depressed and me calling them more frequently than I normally would (every other day) just to ensure they're ok.
This morning I was on the phone with my mum, I was telling her something rather important to me when I heard she had another incoming call. She got all flustered and said: It is your sibling, I haven't heard them in a month - I have to take this. I said of course and we ended our call. However, I feel rather hurt that I was dropped like a hot potato the moment my sibling decided it suits them to call. I need to get my head back in the healthier space but am somehow failing to feel anything other than unappreciated and less important than my sibling which is very immature and won't lead to anything good.
