Hi. I had stretches of sobriety, too. My longest was seven months when I was going to AA.
I found I couldn't do it alone, either.
I hope you find the support you need here. You can stay sober if you're willing to do whatever it takes.
And that's the active word, willing. It took willingness and an open mind for me to get sober and take action and go to any length necessary.
Best to you and I hope you stick around.
