Welcome to HCM
We understand your concerns
I went through your descriptions. I suggest you to visit a physician immedietely to find out the reason for your tiredness
and loss of apetite.
Sometimes it is possible that emotional overwhelming might suppress appetite. But you eat food without feeling the hunger because it is essential. I don't you should not worry about this. But do visit a physician.
Hope this clears the doubts. Available for further clarifications.
