Sometimes it takes a brave doctor to advise a "wait and see" approach, even though it's often the correct thing to do, because patients so often insist on some kind of action. But action, meaning immediate treatment, isn't always best. It's very hard living with "wait and see" if you let yourself think it means "wait until something bad happens", but it's actually a blessing when your condition is good enough that action isn't needed, and you don't have to take on the risks of treatment, just an occasional transfusion. Without knowing the future you and your doctor can't be 100% certain what's best to do, but a lot of patients would be lucky to be able to use a wait-and-see approach.
I have two specific suggestions for you. One is to stay close to the people around you and be honest with them. Let them know you have good days and bad days and give them a chance to share your burden and help you cope. My other suggestion is that you read about MDS in language meant for us laypeople. The best source is the
free packet you can get from the Aplastic Anemia and MDS International Foundation. It's not just about learning some medical jargon. It's to understand more about what's happening to you, let you feel more in control, and let you find the reasons to be optimistic.
