I recently watched this video and I have since found it helps with getting myself to do smaller tasks: https://youtu.be/TVAcs5AHhF4
I wanted to share it in case anyone else benefits too.
If you can't be bothered watching the whole video she basically recommends counting down 5-4-3-2-1 in your head before doing something unpleasant - e.g. waking up instead of hitting the snooze button (it moves your thinking to a different part of your brain).
She also says you should tell yourself you are excited not afraid when you get anxious because they have the same sensation (I don't find this part as effective personally).
