Drinking or using drugs

There is a strong connection between PTSD and increased drinking or drug use, a behaviour often referred to as self-medication. However, this may turn into substance abuse. Substance use commonly includes misuse of alcohol or the use of marijuana, opiates and benzodiazepines to boost “feel good” sensations. These behaviours can prevent you from fully recovering from PTSD. They often mask your feelings rather than appropriately, and safely, managing them.

Avoiding normal activities

In addition to avoiding people, you may also start steering clear of other daily routines that once represented life inside of a comfort zone, Dr Brown explains. “A good night’s sleep has been out of reach for hours, days, weeks, and possibly months, so you may have also stopped engaging in activities that normally brought you pleasure,” he says. This is common. But if you feel unable to function at all, it’s important to contact a physician.
Change in sexual behaviour or romantic relationships

People who are in a relationship and suffer from PTSD often find that their romantic relationships become dysfunctional. They may also engage in promiscuous behaviour. “You’ll probably have problems with intimacy, and likely can’t talk about your traumatic experience because it’s just too upsetting,” says Ken Yeager, PhD, clinical director of the Stress, Trauma and Resilience (STAR) Program at The Ohio State University Wexner Medical Center.
