Yeah, if you're a toddler or a baby or a young child.
I imagine this person is older than that & it is affecting their life a lot if they are posting about it & sounding concerned about this & curious to know what this could be.
Flipping out over small things could be a symptom of a Personality Disorder, it could be a symptom of ADHD, it could just be being sensitive or oversensitive.
The OP hasn't gave us much to go on with just one symptom, with no background info, no other symptoms involved, age, situation, etc.
