<human>: Condense the text into a few key points

I have had pretty severe ADHD for years, and have been on a Vyvance prescription. Since it's been such a regular part of my life for so long, I never thought much about it as a commodity. 

Well, I am in my first year of college, and drugs such as Adderall or Vyvance are in huge demand for people wanting to cram for test or bust out papers for class. 

It started out small. I basically have no privacy in college; I live in a dorm with a very open floorplan. My roommate was the first to find out I was taking it regularly, and it slowly spread from there. People started asking me if I was willing to part with any, they had a big exam coming up, yadayada.

I was hesitant, but it was mix of not really understanding the gravity of the situation and also wanting to make friends and get along with everybody on my floor, but I started giving some pills away. This was the fuel to the fire. 

Soon, as I made it clear that free pills were a one time thing for some close friends, I started getting bribes. "Friends" would buy me campus lunch in exchange for a few pills, that kind of thing. I started getting texts from strangers who were straight offering to buy some. 

It's getting out of control, and I am getting some sort of reputation for dealing Vyvanse on campus. 

Reddit, how do I make this stop without losing all my friends? I've had a lot of people just guilt trip me when I've said no in the past, or not invite me out anymore until I caved and gave up some pills, and then suddenly I was back in the group.

I feel really isolated on my dorm. Whenever people strike up a conversation, I'm never sure if it's just a front to later ask me for some pills.
<bot>: People are taking advantage of my legitimate vyvanse prescription and I legitimately need it to stop. But how do I do this without losing my friends?
