What can be done to deal with post traumatic stress disorder on my own?

What to do: I will start w a deep breathing exercise that you can do if you are becoming anxious or irritable. Breath in deeply & slowly through the nostrils. Hold air in lungs for a 5 count before slowly exhaling through an open mouth. Repeat until you are calmer. Focus on your breathing not what is making you upset. Getting physical through aerobic activity is an excellent way to help keep anger in check &.
