Do I have Avolition? If so, where do I post to?

For some time (as long as I can remember really), I have had trouble motivating various behaviors, such as school work and hobbies and such. In particular, I find these pursuits worthwhile, yet fail to initiate them.

I often fall to mindless distractions, but even when I eliminate the distractions, I will just stand around doing nothing. (I would be willing to eliminate the distractions if it helped, but seeing as it hasn't helped, I usually don't.)

In particular, when I go to do a task, it feels like there is a minor pressure in my head, and I simply don't do it, almost as if my free will is impaired.

This causes me great anxiety, for I feel like I am wasting my potential. I can even cause me to feel sick to my stomach.

Note that it isn't that the tasks are too difficult. The above symptoms aren't completely continuous: there are breaks in it, and I have little difficulty ability-wise in completing them.

This seems to describe Avolition (https://en.wikipedia.org/wiki/Avolition) and perhaps related symptons. Does that sound right? If so, how should I proceed?

(I could wade through psychology papers to find a solution, but the problem is that the problem is recursive. I'm lucky I was able to post here without losing motivation first! Once it is even 10% solved, I will be able to take control and find the most effective places and methods to get help, but until then I turn to you.)

(For full disclosure, I have asperger's syndrome, and recently it is believed I have depression, and am taking medication for it. I am not too concerned about these though. Avolition seems to be the root of all my troubles at the moment.)
