Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.
good luck!
I, like you, wanted a "fixable" problem, and bizarre as it sounds I hope your tests throw up anaemia or a hormone imbalance, because there's a tablet for that. However, prepare yourself for the chance it could be all down to depression, and in much the same way that you wouldn't run on a broken ankle, don't stress your mind too much. If possible, try and take some rest days.
