Hello Krow.

I can relate to what you are saying, I too can caught up with all sorts of things that only makes me more resistant to go forward. I almost gave up on my last year of uni studies because of it. This is what I was told to do, and it worked.

Write on a piece of paper, in big letters, what your immediate goal is, such as the new college you got accepted in. Put that piece of paper in front of your work space, as a reminder of why you have to do, and need to do, to get there.

Now refocus.

Your new college requires you to pass high school to a certain level. It does not care about anything that is happening in your current situation. All they care about is not losing you (giving up) in their college. They need that you can 'focus' on the task at hand. That is, do what is needed to do, to pass.

It does not matter if we cannot see the purpose of what we study. Somethings are there just to prepare our mind, to think in a certain way, so we can grasp the next/future lessons, even if those lessons do not seem related to it.

Some lessons test out patience, tolerance, ethics, etc. All these too are skills that cannot attained by reading, only by practicing them.

Refocus on procedures only. Don't worry about the results.
If we worry about outcomes, and results, we are not focused on what we are supposed to do to finish the course. As a result we will talk ourselves out of finishing.

Refocus on procedures only, and the results (reaching your goal) will take care of itself.
Whenever you get fed up, fearful, tense, about what you are doing, look at your message in front of you. Remember this post, and refocus.

I truly hope you will let go of "what is not needed to pass", and refocus on "what is needed to pass".
Remember, your new college expect their students to be able to do this, or else they won't finish.

Hope this has helped you Krow.
