Trouble is with elderly parents, the child has to grow up and take over the responsibilities, as the parents regress into a childlike state…. both mine did anyway, maybe it isn’t the same for everyone. Also my brother didn’t cope well with it all. So I definitely felt like I had to toughen up and support everyone, even though I was the youngest. Similar with my mate in many ways, I definitely became his big brother as best as I could. You’re right though, you still have to think about your own state of mind, and talk to loved ones about the whole thing, something I’m crap at. I definitely hold it all in.
