That critical voice is your sneaky, lying alcoholic voice. It's setting you up for the weekend. When Friday rolls around, it's going to say all those things, and then add that you should just have a drink to get some release. My AV was the same way. It didn't urge me to drink all week. Instead, it told me that I am a terrible father, a terrible husband, a bad friend, and a total waste of space. Then when the weekend came up, I was all primed for a three day pity party bender.
You're still in early recovery. That critical voice will fade as long as you don't fuel it with more booze. Your self-image will improve the longer you stay sober, and you will be able to meet your challenges, instead of drowning them in booze every weekend. You have permission to focus on your recovery, because that is the key to unlock all the rest.
From another weekend binger, good luck this weekend. Stay strong, keep posting and make it through.
