it's def hard, it will a very long time to heal. But once you get over this learning phase it’s easier to analyze why you were wrong. It’ll be easier if you blame yourself instead of the other person because thinking about the past will only hurt you more.
take time to grieve & cry
if its to refuse the product, the best option would be c. give an excuse. however, that method may not always work so i believe b. accept the product but do not smoke it would be the best way out of it. the question is asking for a way to refuse the product so it is more likely to be c because a,b, and d all end up with said person obtaining the product. i hope this helped!
