Physical Body Affects Options

Would it be possible to gather so much energy to the point where it affects your physical body like lets say your strength or color of the eyes?

When you flex your arm muscles they get bigger i used to have to do this but now when i do they just stay the same size when im not flexing. Its like they are flexed at all times. This didnt happen till i found out that my girlfriend cheated on me.

When i found out she did i got extremely angry to the point where my body just started "chugging" energy then turned around and it started giving off this strange sensation along with a headache that came then left during this. I eventually passed out not sure from what but when i woke up my head hurt like i ran into something and surely enough i did end up doing so. I went into my bathroom to see how bad it was and there was not a bruise or anything but my eyes ended up getting lighter. Used to have very dark brown eyes now i have a few shades lighter of brown. As for my arms they didnt hurt very much till i was getting ready for school the next day.

Umm, about the eyes... Changing color isn't all that strange. It happens to all the males in my family. We start off with a green, and go to a hazel.
