Hi there ~
Please visit your doctor to reassure yourself of any condition that you may not have and if it is good news. Also if your doctor has bad news, he or she will also have something to say about how to deal with the situation. Regarding weight loss
and loss of appetite and lethargy
, you might need to consult a psychiatrist
who might help with any psychiatric or psychological condition that might need treatment. I hope this helped.
Take care and have a lovely day!
