Do you think I have ptsd?

Ok so I'm an 18 year old male. And about three weeks ago I got robbed at gun point for my iPhone 7 I gave the guy my phone and everything but I really can't stop thinking about it just earlier this week I was walking down the street and some guy was walking his dog behind me and i started screaming because I thought it was that guy who robbed me again, and I cried when I got home. And now it's very difficult for me to fall asleep at night. And I really don't wanna leave my house anymore. I really don't wanna see a therapist because I really don't wanna tell my family how I'm really feeling

I got robbed at gunpoint?

Someone off a app was selling a iphone 7 plus for a good reasonable deal. He said to meet him at his apartment complex. I parked in the car waiting for him to come, 5 min later he comes to the side of my door demanding all the money i had in my wallet. I had about 650 $ frozen in shock. I called the police and they were searching for him i have gave them all the details. I'm very traumatized this never happened to me out of all the yeara i've been buyimg phones. I live paycheck to paycheck, are they gonna catch him for sure? Can i sue him for robbery?

Charging your device over night safe?

My mom just saw a news headline that said some girl died because her iPhone exploded while charging. On top of that the news had a few pictures of other victims. Now she wants me to not charge my phone on my bed stand because its too close to my bed…

Is my mom just overly paranoid or is taking such precautions necessary?
