Should we be resentful about becoming a carer?

Following on from a previous thread and also a telephone conversation I just had with a professional person who I have financial dealings with, first 5 mins of conversation was about how stressful his life had become, because his parents had started to need help after major operations and general age related ill losing obviously much loved pets.
I was a carer for my mother and after she passed away age 95, my DH had a major stroke which has left him with mobility problems among other things. So I have done my fair share of care, Yes I find it stressful sometimes but I hopefully don't feel the need to tell anyone I come into contact with my woes.
But we are all living longer so therefore we may need assistance of some sort as we age. We hopefully loved , cared and supported our children so hopefully they will support us when we need it, I have discussed( in a jokey way) with my only DD that I am happy to be put in a care home when I need that support, although I know from experience you still need some support from them even in this situation
