Asthma acting up

I woke up this morning breathless...I realised I have lost my ventolin inhaler and ran out of Singular tablets...I was about to change into work clothes when I paused for a moment to think that I better not take the chance. My health is more important. Saw the doctor. The medical bill amounts to 71 bucks. I depend on Singular tablets alot although they cost a bomb. 10 tablets for 21 bucks. :(
