That is procrastination!! I have the same thing. When I was in college I could never do work in my room, or really in my house. I made myself go to the library. When i worked , ok when i tried to do work at my house every min or so I would get up decide something needed to be cleaned, decide i need to see what this makeup would look like on me, what this outfit looked like, etc. the list went on and on! I finally made myself go to the library where there were a lot less distractions. Well ok i found some such as checking my email ever FIVE mins, but eventually i worked through that one somewhat. I definately got a lot more done when i was not home. So...if you have the chance to go elsewhere to work on homework its worth a shot.
Also, if anyone does have advice I could still use it. ALthough i made it through college, i do that same thing at work. I will but off the simplest task!
Here is a saying i learned in college............why do today what you can put off until tomorrow............. now i am not saying you should do this!!!!!!!!!!!! But in school it always sounded so good and made me laugh, so i had to share.
good luck and let me know if you get any ideas! Just know you are not alone
