Shoot yourself wihtout thinking of anything

You look at the gun in your hand for a moment before you feel incredibly stupid. You can't believe you actually thought that it was going to work. What a dumb idea, how did you even think that it could be real? It's probably just some sort of scam for dumb people like you. You mentally berate yourself for being dumb like that.

However, you still feel the urge to shoot it at something, though, and decide to do it to yourself in your irrational, anger-driven state. You don't even stop to consider consequences of it being real and you shooting yourself with it, and you quickly turn the gun around, aiming at your chest, ready to pull the trigger and fire it. You don't even think of any stereotype or anything as your fire it, just to spite the gun and it's supposedly intended purpose.

You are shocked and surprised when a light beam shoots out of the gun and hits you square in the chest. You are even more surprised when the world becomes fuzzy and you start to feel dizzy, and a bright light engulfs everything, and you seemingly black out.

When you open your eyes again, several things seem to have changed around you, but what you notice most is how you feel. Your entire body feels different, and you are sure, much to your absolute shock and horror, that your body has changed quite a bit.
