I've paid for my own health insurance ever since I became an adult.
If you don't have an HSA (Health Savings Account), consider setting one up. It's a very good deal.
I remember the day I phoned my dad and told him I didn't need any more support (I was in college at the time). It felt good to do that, it sure felt like I'd gone through a door. Interestingly, at that moment my dad switched from telling me what to do to advising me, and became my most trusted advisor.
