It sounds stupid but there are thousands of moments I wish I could relive and chose another option, then my life would be different then it is today so I question it.
There are actually two moments that I can't really chose from, ones quite emotional for me and the other is something I don't know If I could ever feel that way again.
One moment would be from when I was around 11, I got so angry that I slamed a sliding door, (a very long story short) and the top bit of the door actually broke off and fell onto my mums head and messed up her eyesight pretty badly. I would want to relive this moment just so I could have calmed down before I walked out that door and maybe she wouldn't have had some problems.
The other would be when I finally washed over me that it's ok being me. I was lying in bed in the middle of the day on January 1st this year, after being accepted by a friend the night before just for being me, not for the mask of something I'm not. I wish I could relive it just so I could feel the calmness, being hopeful and actually being happy for a split second.
The feeling went away as soon as I left my bedroom and it hasn't come back but maybe one day it will.
