I also experienced multiple relapses during the first year of diagnosis. My neurologist and his nurse host a monthly newly-diagnosed patient support/education group. I remember being the ONLY one in the group at the time who had to go through the IV steroids twice in 6 months. That was not fun.
Like Laura says, it does take at least a year to begin to get a handle on the disease emotionally and physically. If you haven't started a disease-modifying drug, please do talk to your neurologist. And then give it time to start working. Call your doctor whenever something new or changes come up. Don't be afraid to ask questions.
Also, some people may disagree with me, but I suggest that you allow yourself to fully feel the emotions which you have. Don't try to stuff away the fear or anger. Acknowledging how you feel honestly can help you to get a good hold on the roller coaster. Be patient and kind to yourself.
Be well, Lisa
