How much does it matter "how hard it is"? either you are going to get "on track" or you are going to accept defeat and settle for second, third or fourth best. Good Luck whatever you decide.
As long as you sit your mind on bettering yourself and achieveing great goals then that is exactly what you will accomplish! You are in control of your life and whatever you make of it is your choice. Keep your head up and maintain a positive attitude, by shooting for the moon and you will end up hanging with the stars.
If you're talking about how hard would it be to get a job then not hard at all...most employers don't ask or care about what type of discharge you had unless it's a government job.
