Sometimes I think we see ALL our behaviour as unusual, or different to the norm.
In this instance I can tell you I have seen 'normal' people (whatever that means!) behaving in a similar way, doing similar things... And although you allowed the situation to frustrate you, it wasn't THAT bad.
I think I had a meltdown last night...although mine are so common they're just normal at the minute
Partner was shut off from me, I couldn't read her mood, I asked and didn't feel listened to... Basically it escalated and culminated in me smashing a saucer on the floor, walking calmly upstairs and making a blanket tent over myself to shut everything out.
I hope reading that regular occurrence from me helps you feel better about yours...especially as yours are so rare!
Also remember we're not nightmares all of the times we have some great characteristics that make us great fun and interesting to be around. But, I agree, we all need to work on it!
