Don't let him get to you, OP. On a side note, discuss this with your band teacher.

This time, at band camp...

The choice of background image was a bit unfortunate, covering most of (I assume) 'asthma.' The situation sucks, though.... Sorry that happened.

Asthma sucks, doesn't it? FYL.

Student: I'm adept at playing an instrument. Teacher: I hear you, literally, but....can you just run around this field for a bit?

as someone who also has asthma I feel u, bro

Ah, yes, the joys of being shamed for being "fat" or "lazy" when you have legitimate medical problems that make exercise agonizing and potentially deadly. I'd like to take some crowbars to some kneecaps and make them run on it, and see how they feel about it then.

That used to happen to me a lot in school, only I wasn't diagnosed with asthma until I was an adult. I was constantly berated for being "lazy" and "unfit". I just assumed this was true and sports weren't for me until I recommitted myself to fitness as an adult and finally figured out something wasn't right. I find that taking my ventolin before exercising REALLY helps, and figuring this out changed my life and opened the door to stuff I could never do before. Don't let nasty high schoolers (or nasty teachers) put you off basic fitness. Even though you are not an athlete, you will find that being multitalented in music, smart AND fit enough to enjoy stuff like hiking or tossing a frisbee around will eventually put you miles ahead of most people---Even the high school athletes, who often end up injured or obese in adult life. Not to mention how improving your cardiovascular health can help you as a musician. (Singer/string player talking here!!)

I'm sorry for your asthma... but people don't say "fatass" unless you're fat. It had nothing to do with your asthma, just that you eat too much.

Sounds like that dude is a asshole though don't let him make you feel bad :v
