Being 24 years old I had never really had a meltdown. I have been having meltdowns as of late. For some reason I never got them when I was younger. I have these meltdowns as a response to people not understanding me. If I say something and people don't get it ... And repitition is not enough then I will crack. Is this uncommon? Normally I hear people have meltdowns due to a sensory overload. Do others have them for reasons other than sensory overload?
