We understand your concerns
Unknown cravings and feeling of addiction to things which are not actually addiction forming or are not actually addictive are a sign of Obsessive Compulsive disorder
(OCD). These could be due to the extreme stress you underwent. could be Post Traumatic Stress
Disorder (PTSD) induced OCD. You must be able to remember what is that stress situation and approach a psychologist
/ psychotherapist for treatment before reaching a Psychiatrist
. I can help you if you desire so. Deep Breathing technique and meditation could also help.
Get well soon.
