Welcome to PC Zircle!

It is difficult to feel motivated when not feeling up to par. I know when I am not sleeping it really affects me. Exercise, as strange as it sounds, has helped me with sleep in the past and eating well. Also, have you had a chance to talk to someone, your doctor or even a counselor, about recommendations for sleep and even about what is going on by chance (?). Sometimes the stresses and other things can sneak up on us and comes out in other ways affecting studies and concentration. Take good care of you in the process.

I also had to drop my studies down to fewer credits/hours. I have had to learn to focus on smaller tasks at time and not to jump too far ahead of myself. If I start thinking about all the things I'm not doing or looking too far to the future, it paralyzes me. So I do one thing at a time, what do I have to do in this moment, and very small steps, so that I can feel some accomplishment in the process. I get a few pages done and a break, then a few more. Based on a study that was done, a school advisor recommended to me not to study more than 25 minutes max at a time or even smaller then break for 5-10 minutes and go back. I don't know if this might help you too right now but I know I started with a smaller time, don't go over it, break for 5, and come back, then work up to 25 minute increments until you get your concentration back, sleep better, and feel better.

While focusing in the moment, it is difficult to stress about the future and easier to concentrate. You can do it! Hang in there. Sending good wishes your way.
