I have a lot sympathy for your situation and I am sure you have been worn down by stupid advice from a lot of people. I sometimes have depression and I am tired of advice to “lighten up”.

But let me just repeat: I believe that if somebody has sleep problems it’s worth as a first step to try going off caffeine. There is no guarantee but it will help a lot of people but not all.

Have you ever tried cutting caffeine out of your diet?

I’ve had lots of periods (from months to years) in my life with zero caffeine.

Including all of my childhood, and I’ve had the sleep problems all my life. Think about what that means for what you’re saying.

Yet people like you are so sure it could be the cause or contribute, and that I could never know without cutting it out of my diet.

Even aside from what I mentioned above, if you experienced what I experience you would know that it couldn’t possibly influence why I have sleep problems.
