I have a massive crush on my doctor, and i REALLY need it to end.?

Okay, so i started going to this clinic because i had headaches and felt mildly depressed and i ended up being diagnosed with moderate to severe depression. Anyway, i wasn't expecting to get a handsome doctor, and i did, so now everytime i go, when the nurses take my blood pressure, my pulse always comes out to 140+. It's BAD. He's the first person i think of when i wake up and the last one when i go to bed. He's so nice too, and i get that he should be, he is a pediatrician. (I'm 16 by the way) Anyway, yeah, that's kind of the situation. I don't know why i like him other than the fact he's immensely attractive and sweet. I REALLY want this to end though because i know nothing can ever happen between us, although i would not mind it at all. I've been visiting him quite frequently up until now, where i have to see him in a month, and even though i'm looking forward to it, i know i'm gonna panic. This crush is even affecting me focusing on school so i really need it to end. Any advice?
