Hi . It is certainly understandable that if you spend some time on the internet reading about RA it would raise your anxiety. It is terrible that you feel your GP has abandoned you and not given you adequate information, but they did do you one huge favor in expediting an appointment to see a rheumatologist. A real disservice is when a GP tries to handle potential RA cases themselves, without involving a rheumatologist, who has several additional years of training in musculoskeletal and autoimmune conditions. This is not to say they shouldn't prepare you and prepare to work with the new rheumatologist to coordinate overall care.
Concerning what you read on the internet, it is important to remember that people are much more likely to share on the internet when they are having issues controlling a disease than when everything is going well. Treatments have come a long way in recent years and a full and happy life is absolutely possible. I want to share with you this article on the diagnostic procedure, so you have a frame of reference for you appointment: https://rheumatoidarthritis.net/diagnosis. Also, here is an article from Tamara on what to expect from a first rheumatologist appointment: https://rheumatoidarthritis.net/living/what-to-expect-at-your-first-rheumatologist-appointment. Early diagnosis and treatment has been found to make a significant difference in avoiding joint damage (see here for example: https://rmdopen.bmj.com/content/1/Suppl_1/e000057).
I don't want to paint with rose colored glasses. If it turns out you have RA, there may be some difficult times. Finding the right treatment can take time and each case is different. That said, you can absolutely do this. Please feel free to keep us posted on how you are doing and to ask questions. Plenty of people here have been where you are and this community is here for you.
