Good luck chap, you are streets ahead of the Great Unwashed simply as an ex-serviceman. Take the more positive traits that the RAF gave you, dump the rest & adapt to survive!
I left (after 24yrs) just before you joined up - as Edith Piaf famously said, "Je ne regrette rien" - I would do it all again, but better. I would not have wished to miss the experiences I have had (& continue to have) in civilian life.
Life is a game, play it!
