caterma,
As difficult as the decision was, you did the right thing. As you will find with all issues in a flying career, you don't want to spend one minute "looking over your shoulder" to see if someone has caught you doing something you shouldn't. The sleepless nights just would not be worth it.
Better to just lay it all on the table at the outset...fight it out...get that mess over with...and get on to the good things.
You have already demonstrated character. Now fight the b@stards till the last breath to get your Class 1. You have already won.
You will, of course, keep us posted on your progress.
