go to the home page, which is
American Bariatrics Support Group, either on a computer or on your phone, and you can take a screen shot or show your doctor the page in person. If you are in this group and obviously online, you will see an image like this

In the right half of the image, it should show your name, like you see my name in this image, and below that, "Members online" where your name should appear, as mine does in this screen shot. You can also print it out or just save the image as a jpeg or png file and carry it on your phone. If you aren't highly computer literate, you can ask a friend who is, or go to a computer store and ask a tech for help, or your local library can help you.
If you are required to be in a support group like this for some reason, I would take that requirement seriously by posting an introduction to the group, telling your story, and print that out. A support group works best when you participate by sharing your feelings. If your doctor requires you to be in a support group in order to prescribe medication, I think you should be very honest about your level of participation. I don't enjoy having a member here who is really just using "me" and the group to meet a requirement, but won't add to the group and OFFER SUPPORT BACK TO THE GROUP.
I wish you success and all my best wishes.
