I'm sorry you were diagnosed but if there is a silver lining in all this, it is that you now have a name to your suffering and you can now focus on the proper treatment to feel better.
As far as medication is concerned, I am no doctor so I can only speak on my personal experience. I am currently on Xeljanz, and that has been a life saver. I tried all the biologics and they didn't offer me much relief. Prednisone was always given to me when I would flare badly and it also always made me feel so much better but the side effects were hard to deal with.
As far as diet, everyone is so so different with what foods they can tolerate. Again, from my personal experience, I stay away from dairy, wheat, tomato sauce, garlic, spicy foods, processed foods, corn, cruciferous veggies. Overall I eat a lot of fish, organic and just unprocessed food. That is when I feel my best. I would look in AIP diet and LOW FODMAP. Try it out and see what works for you. You have to individualize diet. Also, I found that taking a probiotic was so helpful for me. Along with other supplements like multivitamin, vitamin d.
