The food is procrastinating.
Make yourself complete one task. Any task. Doesn't matter which.
As a previous poster tried to say, go for an easy win first.
Something that can be completed in a couple of minutes.
If you do have ADHD, you can almost certainly go into what's called hyperfocus.
An almost hypnotised state where you lose track of time and just concentrate on one thing.
Break your tasks down into the total number that need to be done.
Write the task down on the top of a sheet of paper, with the deadline.
One piece of paper per task.
Once you've sorted out the total number of tasks, concentrate on each one at one at a time.
What needs to happen before each task is started?
Do you need any equipment?
How much time do you have?
Break the task down into stages and list them in the order they need to happen to complete the task.
Do this for each task.
Work through the tasks with the most pressing deadlines first.
Try to combine tasks.
If you need to go online to find information and another task also requires you to find information, then go online to perform both tasks.
Try to go for diagnosis.
