I have three thoughts on this.
Start with acceptance. You are the one in charge here. Take full responsibility for your own life. Live proactively instead of living reactively. Don't wait until things blow up. Somebody once said "There are some who make things happen, some who watch things happen and some who ask "what happened?"."
Also, don't ask yourself "why?". Ask "how?".
Additionally,
set a series of deadlines.
