I'm glad you are working with your doctor to manage your stress. Getting some light exercise is a good plan too.
In terms of whether or not you're dealing with the OW's sock puppet... yeah, you're dealing with the OW's sock puppet. But you need to remember that it's VOLUNTARY on his part. He's not some poor little muffin who's been preyed upon. He's made hundreds, if not thousands, of small, daily choices to deceive and betray you. It's completely natural for us to try and find a way to explain our WS's behavior, to see him as a victim. But it's just not true. He had agency, and he still does. His sock puppet status is limited to minutia, like the stupid questionnaire he sent you, not to the big ticket items like choosing to commit adultery.
You can't fix him, sweetie. No matter how badly you might want to, it's just not in your power.
Maybe a good thing to do would be to ask your friends to assist you with NC by not sharing information about you with him and vice versa. Your brain needs time to develop new neural pathways which result in habits. It's kind of like the old parable of the two wolves:
An old Cherokee is teaching his grandson about life. “A fight is going on inside me,” he said to the boy. “It is a terrible fight and it is between two wolves. One is evil – he is anger, envy, sorrow, regret, greed, arrogance, self-pity, guilt, resentment, inferiority, lies, false pride, superiority, and ego.”
He continued, “The other is good – he is joy, peace, love, hope, serenity, humility, kindness, benevolence, empathy, generosity, truth, compassion, and faith. The same fight is going on inside you – and inside every other person, too.”
The grandson thought about it for a minute and then asked his grandfather, “Which wolf will win?”
The old Cherokee simply replied, “The one you feed.”
Right now, your neural pathways are set up to default to the circumstances you've become accustomed to. But those circumstances have changed and in order to train your brain to accept a new dirction, you need to "feed" the new neural pathway. Our brains are basically organic computers, which GROW. Isn't that an amazing thought? You have control over YOU and over that process as you see. But you don't have control over anyone else's. Other people may influence you, but they cannot change you.
And it's the same for your WH. The OW's influence, hell her actual words, might spill from his mouth like vomit. But HE is allowing it. She's not winning some grand prize, more like prize pig at the county fair. She's "winning" a serial cheater who abandoned his wife and child. She's "winning" a liar who consistently puts himself first and who sees the value of other people in terms of what they can do for HIM. He has shown you who he is and what he's capable of, and even if he ended the affair tomorrow, he's still that guy. He doesn't share your values.
Hang in there. NC will get easier. The more energy you pour into that new neural path, the sooner you'll get there.
((big hugs))
