Should we have a lighter view on sporadic relapses?

In my last attempt, I went 19 days of No PM and 46 days of no P. It was a lot. Right now I'm feeling like shit and I think I went tonight without relapsing the third time in a row due to a miracle.

I wonder if one could take a lighter road towards recovery if, instead of taking all the guilt and shame of failing, assuming that failures happen. For me, at least, today was a terrible day. I almost had discussions with my wife each time she was near me. That's because it's sunday (and I hate sundays because they're officially the "do-nothing" day, and I hate being idle... I even washed the bathroom at 6pm today) and because I failed yesterday.

So, I'm wondering if I can face the challenge lightly, understanding that to learn to walk one must stumble. Intead of whipping my own back, here or IRL, I should look at it in the eye, accept my failures and move on.

I think accepting failures is harder than assuming guilt. The difference is slight, I know, but it exists. Maybe that's why everyone just bashes themselves over failures that, sometimes, isn't as great as the victories they already have had. Is not the streak that really matters, as it is just a number. It's the change of habit.
