I'm so sorry about your diagnosis! It's strange that you're not seeing a neuro. What doctor diagnosed you, someone in the hospital?
The prednisone can really give you emotional instability, which may be some of your problems right now.
What kind of work do you do? There are folks with MS who still can work. It's a challenge, especially juggling a child and home responsibilities, but if you feel able to do it, it really is a good thing to keep working as long as you can. Have you used up all your sick leave? Or perhaps you work in a large-enough company that you'd be eligible for Family and Medical Leave Act -- that's unpaid, but at least your job will be held until you feel well enough to get back to it.
You should also be thinking about ways your company might make some reasonable accommodations so you can keep your job, if that's necessary.
Tell us more about your situation, and maybe we can offer some suggestions.
Welcome to the board. I am sorry to hear of your diagnosis. It does take a while to wrap your head around something like MS. Good luck with everything you are going through. Feel free to ask as many questions as you need to especially if you start a progression therapy. Kiss that baby girl for all of us and enjoy her. Keep posting and let us know how you are doing.
Love and prayers,
