I once blew up on my older sibbling recently. We reconciled for peace-sake but I still feel good about it. I got a lot of things out of the air:
1) As the youngest sibbling, I got tired of my older sibblings guilt tripping me to spend all of my free-time caregiving, whilst they comfortably live with their wives and children.
2) I let them know that quite frankly, they DO NOT understand how busy a doctor's schedule can get, and since my fiancee and I are both doctors...it is selfish on my older siblings part, to expect me to cancel plans with my fiancee for the sake of care-giving. Sometimes I only get to see her once every fortnight, and my family still expect me to leave her and come take care of my mum.
3) I loathe being told "just deal with it" whenever I say I need a break to recharge. It is basically, an extension of the whole "man up" mantra....men aren't supposed to complain about anything ...so if you are a man, and caregiving for your elderly parent it's not supposed to stress you out, you're just supposed to "deal with it."
4) They do not respect my personal time. Without getting explicit here,I am a red blooded hetero adult male. Can you imagine how frustrating it is, trying to get some action with your SO and your phone ringing off the hook!! The first call is usually some insignificant problem, and the 10x other calls are "Why didn't you pick up the phone?" ... like they cannot fathom the idea that if I am spending time with my SO, I might be "busy."
