So true. People do romanticise it. We don't have DC but we moved my parents in with us 10 years ago so that we could be on hand to help as they aged. Having them close at hand has had its pluses as they used to be a 3-hour drive away and I didn't see them much, but it's definitely had its minuses as well. I'm now into my eighth year of parent caring and pretty much on my knees. At the moment, even without kids in the mix, I definitely fit the description of burnt out and on the verge of a breakdown. I'm about to go part-time at work, which will make all the difference, but it isn't easy, especially as I have my own health issues.
I often feel people give me too much credit. They have a habit of smiling and saying 'Aah, that's nice' when I tell them about the living set-up, but the reality is nowhere near as rose-tinged as some people make it out to be. I do my best and we have help from carers, but it's accompanied by a lot of guilt because I can't always be the perfect carer myself.
