I feel ya buddy. I was in a similar spot recently myself. I was so frustrated. You probably feel like you've done so much positive work to be sober...yet you get zero rewards! You can't even get an interview! It's absolutely maddening and can drive a person into a bad place. I got into a real negative place for a while there while I was unemployed after returning to the States (july-october)...I started lashing out at everyone and began isolating myself, which didn't help. You seem like a more social person so that's good.
Anyway, I hear your venting loud and clear. Keep doing what you are doing, good things will happen.
PS : try the Reddit r/jobs forum, that is a good place to vent and get advice!
