For me I think it's frustration. It turns me into a 5 year old. I'm 37, and this evening I spent literally about 5 minutes trying to map out facial proportions for art work, and when I couldn't do it immediately I got overwhelmed with frustration and anger, threw my sketchpad across the room, burst into tears and ugly cried for about a half hour whilst getting angry that my FP wasn't paying attention to me (although he didn't even know I was upset cos we were in different areas of the flat). I left my room to get a drink and he saw me and my puffy face in the kitchen and showed me a funny video which cheered me up...until I went back to my room and the tears threatened again.

Sometimes I'd rather feel nothing at all than be totally taken over by shit that I KNOW isn't a big deal, but in those moments it's like I literally revert to being a child.
