Hello everyone.   


I have had anxiety pretty much since middle school and was diagnosed with ADHD as a kid.   
   
Around 6 or so years ago I had this specific symptom pop up that happens every now and then, it can be rare. I think it may depend on the situation I am in, I am not 100% sure, I just know that these specific moments have stood out to me.   
The first situation: When working at my first job, it was a really busy night, and I was working cash register at sort of restaurant style place. I occasionally ran food to tables. Well, there was this specific moment where all of a sudden everything seemed louder than normal, I kind of felt like everything was caving in on my head and it was overwhelming. I ended up getting tunnel vision at some point for about 5 seconds and then came back to normal. I haven't had tunnel vision since then but, it was terrifying having everything in my vision turn black except this tiny spec of a customer that was standing right in front of me.   
The second situation:   
I was meeting up with someone in a coffee shop for a date and we talked for probably 3 or 4 hours and there was a specific moment in our conversation where everything sounded louder. For a few moments everything seemed quiet too and my date seemed like they were talking too loud and it gave me extreme anxiety. The lights also seemed really bright as well. It almost felt like EVERYONE in the cafe could hear our conversation even though we were both speaking at a normal volume. This particular situation has happened more than once. Once we stepped outside I was fine.   


Are these sensory overload symptoms or should I look into something else?
