Wow! There are so many posts on this site about procrastination - I just answered one so forgive me for cutting and pasting this reply but the message is bang on target...
Your desire to procrastinate comes down feeling overwhelmed and not really knowing what to do next or how to solve the tricky issues within the tasks that you need to do.
Most procrastination can be solved through thinking carefully about the preparation needed in advance to complete the final task. Once you do the preparatory work the final thing generally rolls up pretty easily. The exceptions are when you find something within what you have to do 'impossible' on some personal level. That could be a lack of time, or resources, or knowledge, or skill or uncertainty over making a decision. Identifying that issue of perceived impossibility is the key to dealing with your procrastination. If you don't do that then you will keep turning away from what you have to do because a part of your mind is saying "I can't do this, it's impossible to complete right now so there's no point in bothering, I want to do something easier instead."
Once you grasp this concept and face up to your limitations you feel massive relief because you now know what truly ails you. After that it's a question of solving that essential problem of 'impossible in the moment'
