Most of the symptoms that you have described here suggest a possibility of stress
. If you also have sadness of mood, apathy, loss of interest in the surrounding, etc., you might consider depression
as an additional possibility.
The diagnosis of your condition cannot be done online. You can consult a Psychiatrist
for the same. We also have a lot of 'depression rating scales' that can determine how much depressed you have. The same goes for anxiety, too. You can ask for those.
I could not locate the name of the medicine you have mentioned here. If you have a specific question to ask, you can reply again.
