I don't have quite as much sympathy for you as Richard does above, but I do agree that you have to face your problems.
You have to face the fact that you committed a crime. You saw an opportunity and decided it was "worth it". It was a mistake, and you must be willing to accept the consequences of your decision.
A little deeper down though, you have to ask yourself about what "
integrity" means to you. Maybe this was a single event fueled from irrational thinking, but maybe this is more of a pattern in your life - something that leads you into trouble in different ways, and this is really a wake up call about who you are and what you are all about in this world.
It's never easy to face our darker sides... but it's necessary to grow as a human being.
All I can say otherwise is to listen to your lawyer.
