I'm Not Sorry

Everyone has a past. It's not always the best and the point of having a past is learning from it, being a better person, and moving onwards in hopes of living a better life.
For me, I used to do drugs. Nothing too hardcore, but I did. I'm not proud of it, it's nothing to brag about and I don't do them anymore. I don't even smoke pot. To me pot is not really a drug so much and I don't judge people who smoke it, just that I don't smoke it anymore. I cleaned up myself and my life.
I have lost "friends" because I have refused to hang out anymore with them because of the feeling and emotions surrounding when I did do drugs. This would have changed anyway, no doubt, because they are the kind of friends that are fair weathered, treat others and their lovers unkindly, and always have a negative aura about them. I didn't want that in my life anymore.
So I'm NOT sorry if I'm now unpopular.
I'm NOT sorry that I'm not sinking into a hole like they are.
I'm NOT sorry that I want better for myself.
I'm NOT sorry I didn't reply back to the stupid immature messages sent over web.
I'm NOT sorry that I stopped hanging out and being your ear for problems.
I'm NOT sorry that you are going through what you are going through, it's your own fault and only you can change it and how you feel.
I'm NOT sorry that I'm doing better than you are because I choose to express my emotions healthily by not doing drugs as an escape.
I'm NOT sorry.
