Hello @angdickinson

I would like to join @colleenyoung in adding my welcome to you. This is a very helpful forum for meeting others with similar health issues. As you read the posts of others, I hope you will find something that you can relate to. In addition to the discussion group that Colleen mentioned, here is another one that might assist you,

It sounds as if you have numerous health issues, and the gallbladder surgery added another group of symptoms. As you mentioned, autoimmune disorders, perhaps you will find the following discussion helpful as well.

As you did not mention the type of surgery you had, I'm wondering if it was an invasive surgery or was it laparoscopic?
