My advice to you is to take it seriously. Don't blow it off...I understand you are a busy college student and classes are stressful. The last thing your parents want is a phone call from a hospital in the middle of the nite. If anything I would go and have the pressure in the shunt checked to see if it is normal. As for the apetite issues I really dont know but if that was a warning sign for you as a child then I would say it may be a warning now. My advise is to go to get it checked. Even if it is nothing at least then you will know and that worry can go away. IF you need someone to talk to I am a good listener and I hope this helps. Let me know what happens if you want.
