The great thing about your habit is it helps you hide.
You are focused on your next hit so hit you do not need to focus on your underlying issues.
You do not need to focus on your terrible upbringing.
You do not need to focus on your terrible job.
You do not need to focus on your lack of smarts or atheletic ability.
By focusing on your habit, you do not need to think about anything but when you can use again.
However, since you are focused on your habit, you will never get better.
That is, until you have the courage to finally say I have had enough and it is time to go into recovery.
The world will be ready for you when you are ready.
