Sorry to sound cliché, but first of all you need to forgive yourself my friend. Of course it's okay, relapse is a normal part of any behavioural change relating to addiction. The important thing is to use this experience to better understand your triggers and impulses. Next time you'll do better, remember this is all about understanding yourself better so that these problems no longer hold you back in life. That said, rooting for you mate.
Just try again. It's a process. For most of us, it will come in fits and starts. Get an accountability partner if you don't have one and start a journal. Both are helping me. Don't be too hard on yourself. And I'm rooting for you, too!
Hey Natural, as a relapser myself, I agree with these guys that it's not a huge deal to have a few relapses. You're changing a habit of many years and you're gonna have some setbacks at times. Just keep getting back on the wagon. I've shared this video with several others, but it might help you to get perspective. It's definitely helped me to feel better and stay focussed on what's important.
it's cool! Dude of course it's OK. this is a learning experience and a journey not a destination or goal. ask yourself how the relapse made you feel afterwards, then ask if you want to keep feeling that way. If not ask yourself how you would like to feel then focus your energy on finding stuff/activities that will give you that feeling. BTW, we all want you to be successful.
We have all relapsed at some point. Just remember what triggered it for today and try to avoid that. We are here if you need anything. You CAN do this.
