M41, incompatible with wife F40

I, 41M, have been married to my wife, 40F, for 7 years.

I love my wife I love my kids. I love my life. Our kids are 6F and 3F.

My wife and I are completely, totally and utterly sexually incompatible. I don't even have a particularly huge sex drive, 2 maybe 3 at a push times a week would be more than sufficient.

My wife has what I'd describe as a negative sex drive. At present, it's been 3 weeks since we last had sex. For the past 18 days, the noise in my head has grown and grown, till the point that for the last 10 days, it's been all consuming.

I cannot stop it. Just noise, a shrieking in my head that loops over and over and over and over and over and over. I wake up, it starts. I cannot think, cannot concentrate, cannot do anything but play over and over again the same screaming thought in my head. It won't go away.

I used to be a smoker. Years ago. When I quit, the shrieking in my brain demanding I smoke made me literally burn up. It was my every thought.

This is is the same. Except, I'm not in control like I was with that.

I've had this conversation with my wife once before and basically wad told that sounds awful, I'm sorry, you'll have to find a way to deal with it.

She cannot comprehend that my mind is like this. It does effect her, so it doesn't exist. At best it's just my problem. I have no one I can talk to, no one to help me. I am alone, trapped with the endless loop of shrieking in my own head.

I actually asked Chat GPT for advice the other day. The first line of the reply said it understood how frustrating and this is and how trapped I must feel. I nearly cried. A fucking AI chat bot told me it understood. I know it doesn't, I'm not stupid but it was the first time in my life that anything had said it understands.

I don't know what to do. I am thinking about just completely opting out of sex, cold turkey like quitting smoking. I know the screaming will stop eventually like it did for that. I don't know, I don't know what to do.

I'm so angry, so resentful. And yet if she said come and fuck me now I'd be there like a fucking beaten dog, exploding with gratitude.

I'm so tired of this feeling. So sick and fucking tired. Reading this back, it doesn't go 1% of the way I feel. I cannot put into worlds. I want it to end.

I don't know, how can I stop this? Is there a drug I can take to switch this off?

TLDR - Wife had no sex drive, I have a normal one. It's driving me insane. What can I do to fix this?
