Good i'm glad to hear you will stop.
But doing things like this will not help you to imrove you reputation at PC. I advise having a fresh start and turning over a leaf or two. improve your behaviour and be a little more patient. There's no harm in thinking something through and considering the repercussions. Just explain that it was a mistake and that it won't happen again. There's never harm in apologising on your behalf even if they don't agree with it, just move on.
