Think about it, you want to up end your life, put your family through whatever, leave them for however long, abandon whatever career you are presently in, all so you can feel better about yourself. You were young and dumb and made a mistake. You're 28, you should be mature enough to forgive yourself for **** and not care what it says on some stupid paper. It's not worth it, mate. It doesn't sound like anybody is giving you **** about it except yourself. If you want to feel better about it, see a counselor.
