I'm really not sure if this is just my anxiety or something else going on in my brain. I feel it's definitely related to some chemical being released in my brain when I become excited, mad, or stressed. It happens every time. 

Just now, I said to my grandpa, who was waiting for his ride to come and was saying earlier how, "they're late and I've been waiting for them", "you said you were waiting for them but you're not even ready", because he wasn't ready at all so him saying what he said was stupid. I didn't say he was stupid but when I said what I said, my brain got those weird tingles again. It wasn't even a stressful conversation, it was just me speaking my mind. 

I wonder if it's my brains defense mechanism or something. It's so fucking weird and it happens every day. Does this happen to anyone else? I never admit it to anyone.
