I would help family members and their families, but my friends are all into prepping, so they shouldn't need help, but if they do, we already plan to have a swap and barter deal going on.
It also depends on the situation. If there is a contagion, this could get dicey. I have helped my mom when she is sick, and I have gotten sick in the process of being her caregiver. For her, I would still help, but now I plan to go get her early on if the situation will allow for that.
For me, family comes first. Friends have to hang on their own. It's a hard knocks world. Ant and the grasshopper....
