Hi, and sorry to welcome you to our exclusive club here.
I think everyone goes through feeling overwhelmed and the various stages of grief when they're first diagnosed -- I know I did (several times!:).
If you don't know what your future looks like, how are we to know? :) Seriously, MS is a very individualistic disease. At this point, your life has a new focus on being healthy and happy -- but I think that should be the focus for everyone.
You didn't mention symptoms and issues that caused you to be diagnosed, but those vary and can come and go -- again, it's an individual thing.
merryb53 mentioned knowledge is power and reading a lot, and I agree. After you finish crying, it's time to learn about this disease.
In addition to reading, I'll suggest watching some videos. This doctor
(an MS specialist neurologist in Ohio) has a bunch of great advice about various drugs and MS in general -- highly recommended.
He's got a video specifically for newly diagnosed patients that you're sure to find interesting and reassuring. And there are a wealth of other tips and information that you're likely to be interested in.
Your profile mentioned starting Ocrevus; that's good you're getting on a DMT and seem to have a handle on this. I haven't had any reactions or issues since I've been on that (coming up on a year for me).
This PDF file
from the Swedish Neuroscience Institute in Seattle is a nice summary of DMTs. And this video
from a presentation at the Rocky Mtn MS Center talks about Ocrevus. It has a nice table at about this point
which summarizes some of the popular DMT options. And the doctor mentioned above also has a playlist of videos on Ocrevus
. Those will likely make you feel reassured about your choice.
