You Didnt get laid
If you're feeling down,a session in the gym or swimming pool might freshen you up and clear your head.If you're studying, regular breaks and snacks such as fruit or cereal bars will help you stay motivated and energized.
I don't know, however, you will know something about it and what is troubling you? Try writing down what you would truly like to do, and why not? What is im;portant to you in your life? Make a beginning, even if its simple to improve something you know you hav ability to do, yet can't be bothered, however, if you did take time to achieve something, think of how that might feel, what you would see, and what you might hear....Good Luck!
Low mood ? Depression ? Try to search on google to get clear details :). Hope it help a bit lol
