I'm pretty positive this is related to some sort of overload, but I would just like input and or somebody to just reassure me I'm not a nutcase. This is something I've always had issues with, but for the longest time it was downplayed when I was a child and I was usually dismissed in some way as if I could will the anxious feeling away if I just had positive thoughts. Except, it's not mental at all (sometimes I'm not even in a worried state) and is almost entirely a physical upset. I just feel like nobody understands when I try to talk about it, and it's making me a little sad.
The best way I can explain it is through an example. Say somebody has a really important project for school that they've been working on, they usually says things like "I can finally breath" after turning it in/presenting it/getting the grade back. I never ever feel like a weight has been lifted after something is over if it has upset me to a certain point. Even if I think "Oh, it turned out okay, you can relax now", my body doesn't allow it. I feel like my system gets "shocked". It's almost like I'm helpless to it and usually the feeling just controls me until the stimming and upset wears me out enough for me to go to bed, then I wake up feeling better. It has been impacting me quite a bit in terms of functioning and my relationships especially. I have to opt out completely if I'm talking with somebody and I've been upset by something said or done and I'm not able to reason it out, like I usually try to in a clearer mind frame, even if I'd like to. I think this is just happening more recently because I've been very stressed and all sorts of fun things happen when these times come. I'm sure this is related to aspergers (correct me if I'm wrong), but I'm really just recently coming around to the diagnosis forever after I was actually diagnosed, so I've never quite learned to efficiently deal with things.
