To start this off, I was not a good person. I yelled at my little siblings for no reason, I lied and manipulated people around me, hell, I even threatened to unalive a few kids at school. To put it simply, I was a bully with little empathy. (Side note: I do feel very guilty about my past actions and have apologized and done my best to make up for them.)

I was aware that I was not a good person, and I hated it. I didn't care enough to actually put effort into changing my actions, and I hated myself for that, too. I fell into a pretty rough depression. Self-harm, suicidal thoughts, intense feeling of self-hatred, the likes.

One way I hurt myself was to hit myself in the head, or hit my head against a wall. I thought that it could either change my personality and make me a better person, or kill me, and I was fine with either. I'm aware of how flawed that logic was now, but I clearly wasn't thinking straight at the time.

The thing is, I think I actually did change my personality. I woke up one day, and I was a little different. About a year has gone by, and I'm basically an entirely different person. I had no idea I had changed this much, until I began to think back on it. 

I never took any medication, I never made any attempt at bettering myself, the only thing that it really could have been was me hitting my head against things.

Once I started to think back on my personality change, I noticed more things. I completely stopped self-harming once I started changing. There were no relapses, even though every attempt I had made to stop before included several. I'm absolutely appalled by the person I used to be and can't ever imagine myself doing the things I did.

I'm also much more clumsy then I used to be and get headaches more often. I lose things much more often as well.

I asked my mother if she had noticed any changes in me the past year, and she said I've been calmer and just a generally good person. Is there even a possibility that I could have changed my personality? I'm at a complete loss.
