I think you did really well to hold onto a job, pay your bills, cope with and now deal with a life threatening problem and get a degree ! wow !
I think sobriety teaches me how to be effective at dealing with life .. In a way my life only re-started 2 and a bit years ago for me .. i can't change the past but i can sure make the best of every day i get left on this glorious planet .
You have a glorious opportunity today, i hope you have another tomorrow .. you set yourself up with a win by waking without a hangover
Take care , m
