Feeling down, depressed and unmotivated, any help!!?

Viruses can last for months, and effect you in all sorts of ways. I would suggest that you go back to your doctor and get re-checked. Because you are "out of sorts" you may be putting off negative signals, or feeling like people are treating you poorly. Once you feel 100% you will be able to exercise, volunteer, join clubs, meet new friends, and do all sorts of things. Be sure to eat well, and avoid junk food until you are feeling better. Don't give up - talk to your doctor! Also ask your parents if you can talk to a therapist, that could be helpful. You want to first get better physically so that you can get better mentally. Good luck.
