Given your health, you may very well be phase 2 not 3. You'll still have to wait for phases 1a,b, and c of course, but...you might be able to get in early. I know some states are saying just being obese qualifies you for phase 2 instead of 3 (so, what, 80% of the US is phase 2 now?)

Might be worth inquiring with the medical professional of your choice (assuming you can do so without incurring a fee)
