When you have too much to do, you have to either go nuts or try to engage in an exercise of priority setting. You list all the things you have to do and why you want to do them, and then you decide which ones are most important. You decide which ones you cannot live without. If you think you cannot live without anything on the list, you have identified your problem.
You then have to force yourself to prioritize things. You work on the top priorities, and push off everything else for later. You also put time for yourself on the list, and give that a higher priority. Then, when it’s time, you take time for yourself and put off those less important things.
This a matter of life and death. If you take on everything on your list, and you don’t do it, you run the risk of getting depressed and you know as well as I do what depression can do to people like us. I was able to survive doing this kind of prioritization and also by asking my wife to take on more. I don’t think you have a spouse to rely on, so you don’t have that option, but if you have friends or children, perhaps you can ask them to take on some tasks that have to be done but that you can’t do.
People like us have a real hard time doing things if we are depressed. We’re super efficient when we’re doing well, but depression is a killer. And letting yourself get overwhelmed can lead to depression. So please make yourself be ruthless about cutting things out of your life, and about asking friends and family to take on some tasks. In one way or another, you must make your life feel manageable. You must! And you can!
