I am seeking support groups or meetings of some sort that keep receipts for my records. Does anyone know what I am talking about?

do they have to be in person? Unjury (the protein company) offers weekly virtual support groups and they do send receipts to you if you attend. They have one group for people pre-op to one year post-op, and another group for people over a year out (although people sometimes attend the "wrong" group - the leaders don't really care...). You can check to see if your insurance company or surgeon (whoever is requiring support group attendance) will accept that. I would imagine some do since they send people who attend a receipt afterward. Here's the info:

My WL team has it's own support group. Maybe reach out to your team? If they don't have one (which i would assume if they did you would already know that) but they may at least be able to direct you to one.
