Check your sources and question every person's actions. Keep your thoughts on the future. If you feel beat-down and tired most of the time, it's probably because you're out of shape. Try to eat better and get more exercise than usual. Allowing your health to falter at this time is a terrible decision.
Sleep is the best solution to every problem.
You have been quiet and lurking in the background for too long. If you want someone, tell them and quit waiting for them to guess. Your actions will prove greatly beneficial later. School is obviously a necessity, but if you get too burnt out you'll lose momentum. Try to find a balance between your social life and your professional life - you'll be much happier if you do.
