It is important to understand that the only way to know for sure if someone has PTSD is through being officially diagnosed. It can be difficult for someone to know if they are actually experiencing PTSD or if there is a different reason for their symptoms and behavior. What you should make sure to do is avoid diagnosing yourself, and talk to an expert that can help make the decision on whether or not PTSD is an accurate diagnosis for you.
The reason why this is so important to trust experts in the area of diagnosing PTSD is because the therapy, counseling, and care that is required for PTSD victims is not exactly the same as it would be for other disorders. The reason that we have a complete PTSD recovery program at our facilities is because of how unique the issues surrounding PTSD are and we understand what is required to help.
