I Want Answers

It has dragged on for far too long. For the last three weeks, I have been dead tired and I don't know why. Do I have a vitamin deficiency? Am I missing important nutrients in my eating? Every so often, I am not able to sleep however I catch up with sleeping ten hours, but I shouldn't be THIS drained. Is my thyroid to blame? Am I depressed? It is 6 pm and I am ready for bed, but I must eat first! Help, I depend upon answers to help navigate my next steps. Where do I begin to answer any of these questions?
