I'm so sorry that it's pretty certain that you do have MS.
Indeed, it is a highly variable, inconsistent disease. There really is no way to know from day to day, or person to person, how you might respond, or how the disease may progress in your situation.
As for work: lots of folks with MS work, some at full-time jobs, some part-time. I don't know what your employment laws are in your country, but here in the US, we don't have to declare that we have MS (or any other disabling or potentially disabling condition) unless and until we want to then request some accommodation on the job. So some folks work, taking care to "ration out" sick days so that they do have plenty should they have a flare, or exacerbation; and otherwise work around the daily sort of symptoms that occur. Are you working, now? If so -- you might want to look around and see if there are ways you can work more efficiently so that you can avoid getting too over-fatigued (I see fatigue is already a challenge for you.)
As for driving: While I use a wheelchair, I still drive a regular car, without hand controls. It does have automatic transmission, power brakes (and air conditioning, power windows, etc). but other wise is just an ordinary car. I've had MS for over 23 years, and only have stopped driving for short periods of time, while in the midst of a flare, for example. I hope that will be your experience too.
Michelle had some excellent suggestions about keeping in touch with your doctor. While the appointment is an eternity away!, I do hope you're able to call and keep him informed as to any significant changes in your situation. If things do change dramatically, often they'll fit you in much earlier than the "regularly scheduled appointment".
