That time isn’t wasted at all. You started something very difficult and it’s a step along the way. Did you learn something from falling off the wagon? Because if you did, and you’re able to use it to help further your recovery, then the relapse isn’t a failure, it’s a learning experience. I can guarantee that just about everyone here has relapsed at some point–some of us have done it numerous times. What matters is that you get right back to being sober. Next time you will get more than two weeks. You’ll see. You can do it.

The video in the thread linked below might be of interest to you, so I’m leaving it here just in case.
