Don't give up just yet. Keep investigating options!

OP will be 65 when he retires and will pay about $134/month (2018 amount) for MediCare. If OP opts for a Medicare Supplement (a 
real good idea), then that's another $150 or so monthly expense.
Interstellar Orchard Becky is 
32 years old and is currently (2017) paying 
$18/month for an ACA health plan.
OP, I would not listen to non-full timers. They don't know what they're talking about. However, when you get advice from a full timer, make sure to ask about their health insurance. Medicare? Military? Buying their own? None? Health insurance can be one of your biggest full time expenses.
