Unsupportive/ plexus rant

So my husbands cousin just found out that I have Gd, so what does she do? Tries to sell me plexus. She didn't bother to say anything else just that plexus would help me. I'm so frustrated with the fact that to her my Gd is something she can profit from. Im not about to try to sign up for a pyramid scheme with high cafiene amounts to lose some weight. I don't trust that stuff for anything.
