I know having PTSD is a serious matter but I've been wondering if I have it?

It says that you can develop this when you go through an extremely stressful event in your life.

I got cheated by the person that I depended on. I was devastated. I couldn't eat and sleep. It's almost a year since that incident happened but I'm still having flashbacks. I get nightmare almost once or twice a week. The person that caused this is still with me. I'm hoping that this would gp away but I'm being constantly reminded by even the littlest things. I get really anxious when I remember it even or when I come across it accidentally. I tend to have a bad mood when it happens and I throw an attitude at my boyfriend. He asks me what's wrong and it's still the same f***ing reason. I still didn't move on. Because if I did, I wouldn't be acting like this.

I have tried so many things. I broke up with him hoping that i won't be reminded by it and just so I'll forget because he was the root of cause in the first place but I was wrong, I still get nightmares. Now we're back together and I still get mad at him after almost a f***ing year. I'm just tired of it.
