Does malaise get better once you have the right treatment for rheumatoid arthritis? recently diagnosed and losing hope. have only been on methotrexate (injections) for 2 weeks. i feel like my life is over?

Many respond to treatment & feel better, even normal. How soon cannot be predicted in you. Discuss with your team who I trust includes a Board Certified Rheumatologist. As Yogi Berra famously said: "It is hard to make predictions. Especially about the future." ;-). You may want to spend $20 for 1 week access to uptodate.com and read all about RA as you will do better the more you understand.
