My school probably thinks I'm doing drugs

First day I came in, extremely anxious and visibly nervous. I forgot my stuff in the car and stuttered a bit. Pretty normal, it's whatever. As the day went on, I got a bit stuffy and kept sniffling and coughing, and it was so obvious I was trying to hold both back but just couldn't control it.

Fine, whatever, they probably think I'm a bit sick or it's allergies.

Second day I came in, I was exhausted, only had 2hrs of sleep. I actually started to fall asleep in class and was drowsy asf. Kept closing my eyes and fighting actual demons to stay awake. So I drank some coffee from the vending machine on my break and went to the bathroom to blow my nose so I didn't have a repeat of yesterday. While I was blowing my nose a classmate came in and asked if I was doing okay, and I said yes I'm just blowing my nose. Asked I if I was sure and I said yeah I'm fine. Whatever. Then he went into the bathroom stall and when I was leaving I inhaled a nasal decongestant smelling stick so I didn't keep sniffling and then I went to class a bit with the jitters because I drank the coffee on a empty stomach. But it was only with hindsight did I realize smelling aggressively in the bathroom probably comes off as extremely suspicious.
Don't worry, you're old enough where people in your school seriously don't care to snitch. Even if you did do drugs, no one would probably find out unless the teachers genuinely saw you.

I've been asked plenty of times if i was drunk or on drugs just because i was in a silly mood.. can't even be happy nowadays :Sad:
