I have sensory issues as a result of aspergers. I don't have meltdowns as such, more shut downs. I can manage my own issues but I get very angry and moody over stuff and get very overwhelmed, especially when there is a lot of noise and activity going on. I need time out and quiet afterwards and to just be left alone, which can be bloody difficult sometimes as DCs don't seem to leave me alone and DH always seems to appear in whatever room I'm in (except the bathroom).
I've only been diagnosed as an adult, my family don't know and would never even try to understand so I've had to learn to deal with it myself. Mainly I shut myself off and know what I can and cannot tolerate. I hate loose things around my middle so always have a belt or something that is tight, I hate the cold and feel it badly so I wrap up, fingerless gloves are good and a scarf helps to keep warm overall. Now I have a diagnosis it helps me to understand why I get overwhelmed so I can either avoid situations instead of forcing myself to put up with it or leave when I feel it's getting too much.
With food, I stick to what I know and will eat. If I am going for a meal I'll check the menu beforehand and if it's something I don't eat then I won't go. My eating doesn't affect anyone else but I get very fed up when people comment on it.
Instead of meltdowns I get irritable, grumpy, snappy, moody. When I am like this I just need to be left alone completely and I will get over it in my own time. People talking to me or at me or following me and not leaving me the fuck alone will just exacerbate all of those feelings and make me even angrier.
I hate certain smells. I try not to breathe deeply, leave the room or hold something under my nose that I can smell instead. In work people often eat eggs, which I loathe and the smell makes me gag. I hold my coffee up so I can smell that or leave the room for a bit, which I can't do for long enough so I make a coffee and have that to smell. It's bloody awful.
I work part time for another reason, but actually now I know about the aspergers, I wouldn't want to work full time. I need down time and to return to my house where I feel safe and secure and not have too much noise and people around. I could not leave the house quite happily for days if it was possible, doesn't bother me at all.
Having people around who get these things, understand and take your lead would be hugely beneficial to someone on the spectrum. I get very annoyed as DH has not bothered to read anything about it and often questions why I am snapping because one of the DCs are touching me and I don't want to be touched or they are talking to me and I'm asking them not to, or I'm saying the tv it too loud and he insists it's not. I have 1 friend who tries to understand and doesn't make me feel like I have to explain. To have more people around me who did this would make me feel much less of a weirdo who doesn't fit in and just get on with everything like all the NTs do.
