does the dentist unneccesarily torture patients? they get paid to infilct pain,dont they?

It's really creeping me out. He gave me two inhalers (well, one.

other one my mom's getting because it's like a prescription one) and antibiotics so it wouldn't get worse. Like, turn into something else. It's really hard for me to do breath normally, should I be ok after the inhalers and stuff? I think I'm going to go to school tomorrow since I don't want to miss too much. I'd rather keep my last “sick day” for emergencies. I'm already mad about letting myself stay home today. At least I'll get the stuff to make me better today. Anyway, my doctor told me to drink a lot of water, but I just.. can't drink a lot. It makes me feel weird. So, what should I do? He said I didn't have to, that it'd just make me feel better. Btw.. I'm 14 and this is the first time I've ever gotten sick enough to go to the doctor (even my mom said that). That's why this is messing up my mind so much. So basically, I'm just asking for advice on dealing with this. Thanks!
