I have a extremely mixed feelings on this.

I’m in my 30s, but have several of the major comorbidities, including diabetes and asthma.

Should I have to wait at the very end of the line like the healthy 30 year olds?

Having comorbidities like obesity, diabetes, etc increases your risks from the virus by a factor of 2-4. Being old vs young increases your risks by a factor of 1000. You are at more risk than your peers but still at far less risk than even a person in their 60s.

It's complicated and I generally trust the CDC recommendations to be reasonable judgements. But they're not infinitely fine-grained. The rules in lots of places have healthy-ish 64 year old being eligible at the same time as healthy 20 year olds.
