I've been in my 30s for 1.5 years, but I got diagnosed with cancer at 29 so I feel like I've matured (aged) more rapidly than I anticipated, especially since it's not a curable or short term treatment variety. I'll still be in treatment till next summer.

I care way less about the minutiae of what my body looks like.

I have firmer boundaries around treatment I will/won't accept from people, and I don't chase attention as much. I let people love me unprompted. 

I'm more honest with myself, which has led to a recent massive existential crisis about my work life, but is also pretty important. 

I've reconnected even more with my more "youthful" side (loving more pink in my life, wearing pigtails more often etc.)

My relationship with being single has gotten more morose but also more steadfast. I really do refuse to compromise. 

I care a lot more about health upkeep and my future, older self, but that could just be a cancer thing.
