Thanks for the advice everyone! I feel less guilty already. I even practiced saying no a few hours ago. The guilt is the worse when there are enablers nearby to say things like "when you love someone you should <fill in the blank>, not turn your back". Folks will make you feel like if you woke up in a clean, safe, healthy environment, you should be ashamed of yourself for not giving <the addict> $5 for <random excuse>.
LMAO @ "I don't wanna, and I'm not gonna, cuz I don't haffta!!"
Next, I'm using that one for sure.
