I'm thinking of selling half of my anxiety script to buy other things
How are you going to sell your medication?
I know a guy who could help me sell them
We do need money for so many things so it is understandable that when you need cash to do whatever to get the money. But selling your scripts is not good, people will think that you are involved in bad things and you could get in trouble with the law.
I going to be doing it online, they can't trace it.
Online would be even worse since there is a clear record of a transaction and a much higher likely hood of being caught. If you need the extra money, try to pick up extra hours at work or find something else you don't need to sell.
