I have a lot of problems with procrastination. I have done very well in my (academic) career, but I know I could be so much better if I didn't have problems similar to yours.

One thing that helps sometimes is to pick a very small task - e.g. respond to a stupid email asking me to give a lecture, that I have been putting off, and just get that done. I force myself to sit and think about what I want to say, and then do it. The key is picking a very very small bite-sized task. If it will take longer than 5-10 minutes, I will find a way to avoid it.

So e.g. say - I will wash one plate in my pile of dirty dishes, that's it. And then imagine how it will take just a minute or two, and it will motivate you to do it.

If you can get yourself to do one task, I think it has a positive effect and can start a little chain of tasks that you start to finish. You must start small - the thought of everything you need to do can be very overwhelming.

Good luck. with school. I am betting you will be a better psychiatrist already for having dealt with these issues.
