Could this be a symptom of PTSD?

In 2012 I went to Syria because I’m half Syrian and my grandma lived there so we went to visit her for the summer. During that time there was a war, I didn’t know what kind or why because I was 13 and my parents didn’t want to tell me. I still to this day don’t know why or if there still is a war. Well when we got there we ended up staying for a whole 13 months because we weren’t allowed to leave for some reason. We only went to stay for a month, ended up being 13. It was pretty much an every day basis we would hear bombs and guns shooting. Some days louder than others, I was so scared the house was gonna blow up. We would find bullet shells everywhere. There was one day I was sitting outside with my sister and a bullet flew right next to her and landed on the ground I was so scared I thought I was gonna lose her😔 anyways fast forward to now. I have extreme anxiety. I had anxiety before but it’s gotten worse since that experience. Also what I’m concerned about the most is that im always scared my boyfriend is gonna die one day. I don’t live with him yet and he lives alone and I always think what if he just drops dead? How am I gonna know? How is anyone gonna find out? It scares me to death. Especially when I don’t hear from him for a while. I start thinking the worst possible scenarios. Or I think phone calls from random numbers are people calling me to tell me my loved ones are hurt. Also when I’m walking by myself and someone is behind me I’m so afraid that person is gonna kill me, man or woman. It’s so stressful and the anxiety takes over my body I can’t think of anything else. I always think the worst 😢😢 is this considered ptsd? Should I look into therapy for this?
