Hello and welcome to Healthcare Magic. Thanks for your query.
I understand that you must be going through a tough time trying to deal with your depression
. Now, most countries have specific protocols which determine the necessity of companion animals. Usually, companion animals are provided only when the person is having a significant disability
due to the illness, and is unable to manage his / her activities of daily living without external help.
So, this decision is entirely upto your treating doctor. I would suggest that you try psychological / behavioural therapies for your motivation problems, in addition to your current anti-depressant medication.
Wish you all the best.
Dr. Jonas Sundarakumar
