Usually, my anxiety is just me panicking very slightly because my Dad is taking too long to get back to the car and I worry that something bad happened to him. (this anxiety and concern for him started four months ago after he crashed a motorbike while on a road test because of a deer while I was at a friend's place.) 

But three days ago (I've been reluctant to tell this story on here) me and my dad went for a walk with my dog and he was going to get something from a friend (I think it was a friend of his) So, we get there and he says he'll be right back. He then gets out of the car and walks up the stairs to this house.

There was another person at the top of the stairs (looked like they were struggling to get in). I don't know if they knew each other based on their interaction (and I was too far away to hear anything) but they both went inside.
I waited and everything seemed normal, but then after a few minutes, that guy came hastily running out, got in their car and left. They had also left the door open to the house. I found all of this quite strange.

I waited a few more minutes, but my Dad didn't return.
I don't really know what I experienced, but it was not nice.

I began getting worried. I tried to unlock and open the door, but I couldn't. I think this added to my anxiety because I was trapped. I began getting more and more worried. It felt like my heart was racing. I began banging on the windows, not hard enough to break them, but hard enough to make a sound. It caught no one's attention.

I pulled my dog to the front of the car where I was sitting and tried holding her to hopefully calm down, but it didn't work. A few more minutes of panicking and I finally remember the button beside the steering wheel that unlocks all the doors. Figuring out how to lock the doors was not one of my priorities so I picked up my dog and ran inside.

The house looked ever so slightly abandoned, which made me even more nervous. I called my Dad's name and eventually I heard his voice. I called his name again and then a door opened behind me and there he was. I knew my irrational fear of him being killed was going to be awkward to explain so I said I felt this weird sense of dread. We left, got in the car and went home. 

I don't know what exactly I experienced, but I just really needed to talk about it.
