For years anxiety/fear-avoidance cycle defined my life. I tend to procrastinate to a such extent that causes problems in my day to day functioning, and generally my life.
For example, i have to submit 2 fairly simple assignments, in 2 and 3 days respectively. If i don't pass the next 4 assignments i will fail the lab, but i keep avoiding sitting down with all of my power. I feel pure fear and a sense of "i will certainly fail if i try".
The above example is with these assignments, but this type of behavior extends to everything in my life.
