How's the state pension over there? Here in the UK its pretty good, if you have paid off your house anyway. I would be richer than I am now from working if I had a pension but no mortgage.
If you also had to pay housing then it could be kinda rough, but I have lived alright on less.
Running on the assumption this is authentic and heterosexual, Anon's parents massively dropped the ball creating an adult with no will to fly the coop. But then to cut them off cold turkey is totally fucked up. Anon is now permanently 15 years behind their peers. Not to mention zero retirement savings. That compounded interest takes 30-35 years to really start to matter. But Anon gets to miss out on 15 years of that, too.
I really hope things work out in the end.
