Hi Annika,
The short answer is yes, if you do have RA, don't lose hope and think your life as you know it is totally over because it isn't.
The longer answer, and one of the reasons why there is conflicting information everywhere you look is because it is a difficult disease and is different for everyone, and fluctuates for most of us at times.
I am 30 and was diagnosed a little year ago when I turned 29. I felt nothing but utter gloom and doom after I was diagnosed. All the books I found and a lot of what I found on the web (I sadly didn't discover this site until much later) were filled with the words disability, degenerative, progressive, etc. and it seemed impossible to feel anything but despair, fear and, well, pain. I thought my life as I knew was over-I'd have to toss out my heels, quit drinking, and wouldn't be able to do my job or anything else I loved. I"m happy to report that that has not been the case.
I don't want to sugar coat anything-living and managing RA can be very difficult, and as I am learning, has its up and downs. It will change things, but not everything. It's still possible to be active and do the things that you love-you just have to be flexible in how/when you do them and how you prepare. There are a lot of crazy meds out there that have really revolutionized the treatment of RA, and many many people are able to find a combination of medicines and other treatments (yoga, diet, acupuncture, etc) that help them get their RA under control, including me.
Most of what I write for this site has to do with exactly what you talk about-figuring out how to have RA on my own terms as much possible as a young, single, active woman.
Good luck with seeing your specialist-this is a naturally scary time, but this is a great community here. Please keep us (me) posted and feel free to write with other questions or thoughts as you go through this.
Take care,
Sara
