It's all about going at your own pace and doing what works for you, Evey. Others may have opinions but what you feel and think is what really matters. It's your life and your choice on how to overcome the obstacle of your own addiction. Don't let others opinions bring you down or question what feels right to you. Downplaying any addiction isn't right. I don't care what the substance was, it was ailing you and you found something that has made your life easier and more manageable in a positive manner.
Be confident in yourself and your own plan. Others may have opinions, and we can't stop them from having their own opinion on the matter. If you can, try to ignore them if they are interfering with your recovery plan. Just remember that you can't change what other people think, it doesn't even matter, what matters is what you think and feel and what you know is right for you. You don't need to defend yourself for something that is working and affecting your life in a positive manner.
