What I'm about to discuss is a bit difficult to explain, but I will try my best.
I get overwhelmed easily, by a lot of things. But - and I first noticed this a few years ago - I get overwhelmed by things that the average person takes in and processes naturally (mentally, I mean). For example, say I am at a movie with a few people and we are watching the trailers. After the first trailer is over and it launches into the second trailer, I find myself still thinking about the first trailer, even up to halfway through the second. It takes me a long time to process it. I go over the details of it certain things and if there is something particularly interesting to me - say, for example, my favorite actor is in it - I can't seem to let it go. Process it and move on. It sticks in my mind and I must continue to think about it.
I am this way with many, many things. I hear a tidbit of a familiar song on the radio and the feelings it evokes in me - perhaps having to do with associated memories and such - linger and then I find I can't seem to... calm down from it. A certain part of my brain is seemingly stimulated to the point where I can't let it go, it actually becomes distressing sometimes and makes my anxiety go up. I almost feel like I'm autistic at times like these, where the smallest sensory input makes me crazy (whereas the average person would make a mental note and move on, no big deal).
This causes me to feel overwhelmed and overstimulated a LOT, as our culture is made up of a constant barrage of images and sound bytes, EVERYWHERE. It makes me crazy.
I'm not sure if I have ADD, at times I have been inclined to think I might, as I have some other traits that fit it (such as being disorganized and cluttered), but I don't fit all of the symptoms (can't remember which ones I don't fit now).
Maybe it is OCD? I do seem to be obsessive when it comes to certain things, but I don't have any routines such as handwashing or lock checking or anything.
Anyway, I just find it too much sometimes. When I go shopping I am overwhelmed by all the choices. It takes me FOREVER to decide, and I start to feel panicked because of all the input my brain is receiving - so many different products, all offering different features and different prices; too many variables, too many pieces of information to absorb.
I don't know what's wrong with me :

: Music, movies, shopping, conversation, reading... many things do this to me. I have to sometimes just retreat to a quiet area and sit in silence and breathe because I feel like my head is going to explode, I can't contain it all.
Anyone that can relate? It would be great to know I'm not the only one...
What do you think?
