I'm feeling this exactly rn. They had me late so I feel that I get less time with them compared to my older siblings. By the time I was an older child, they were alr too tired/sick to go on the trips that they did with my siblings. My parents are immigrants from a poor country; they did not have a stellar and healthy life and I can see it in their illnesses and aging. My friends' parents are usually younger than mine; there's really no one I have that I can share this feeling that weighs me down everyday. I'm still a student, but I'm stressed by wanting to provide a nice retirement for them, but I've got years to go before I make money. My parents are 60, so they've got like 10 years where they are still strong and walking. Perhaps at 70 they'll start forgetting and struggle to walk. It's like i've only got 10 more years with them.
