Hello and welcome to Healthcare Magic. Thanks for your query.
Even though you have had only one episode of what appears to be depressive symptoms, it is important to have a proper evaluation, in order to have a proper understanding of your problem, so that appropriate remedial measures can be initiated.
Moreover, you say that you have been through a very stressful time of late due to your multiple situational problems. You also don't seem to be adopting healthy coping strategies for handing your stress, for example resorting to heavy drinking.
So, I think it would be worthwhile to seek professional help from a psychiatrist
for a detailed psychological assessment and further management.
Wish you all the best.
Dr. Jonas Sundarakumar
