It is not the end of your life nor does it mean the end of your career.
There just to many variables, such as if this was the only real dumb thing on your record and you face up to the fact that you made a very grave mistake and go on with your life and never repeat offend in any way, I am sure your career is salvageable.
I am willing to bet that a lot of those who pass judgement on others are also guilty of making the same mistakes, just didn't get caught.
Think about it, and all the best.
