I'm finally done with drinking and drugs
Are you done for good, or just done for now?
I am a logical man, I've decided to be done for good this time
If you stick to your logical decision to get healthy, you will be rewarded and should live a happier life.  Other people in your life should respect you more and will want to be around you more if you get healthier.
Anyone saying that I need to get better is a loser to me.
They are not losers, they just realized what you know now before you.   If you talk to them and share what you want to do to improve, they should be supportive.
