Every day you get 86400 minutes offered to you. You can either not do anything with it or use it to accomplish your goals.
Time is on of the only things you can't buy. Every one is equal on this level, this si the most precious and the most volatile ressource everyone has.
But first you must define your goals precisely.
So stop whatever you are doing, get a piece of paper and write what you want to accomplish within 1 week, 1 month, 1 year.
That done, try planning your week ends so that you get shit done and eventually your accomplish your 1 week, 1 month, 1 year goal.
Helpful to keep to you schedule : identify your "time stealer". All those things that wast your time like useless tv, uninterested facebook posts and so on. Realize that every minute you spend doing something you consider useless is wasted.
Then, most important, try getting some rest BEFORE being tired : that way you won't procrastinate in the "I might rest just a little while before i get to it" spirit.
I hope this can be helpful to you. I just spend the last year trying to get out of the loop you're talking about so I know exactly how you feel about it. I'm succeeding one little step after the other.
It's a lot of discipline, but I can tell you the trip is worth the effort.
