You'll soon find that those little things will add up to the enjoyments that make life worth living. Take it one day at a time, and let the diagnosis sink in. You don't have to absorb it all at once, just pick a piece of it at a time to absorb and make peace with. This week, you can choose to learn to accept that you will have low moods. Have your T (or pdoc) teach you some skills to handle the low moods. Next time, choose to accept that you will have high moods, and learn what to do about them. Before you know it, you will have made peace with the whole disease, and picked up a good deal of coping skills at the same time. Just one suggestion on how to adapt.
