Nobody is denying sleep training can help.
But I truly don't believe OP has out enough actual effort into gentle sleep training and CIO extinction method is absolutely barbaric
OP doesn’t have to prove she has ‘tried hard enough’ at a method you deem suitable before she is allowed to move onto extinction.
You speak with a lot of confidence for someone who knows so little. Here’s some info to educate you.
No peer-reviewed research has reported detrimental effects from sleep training.

Here's a look at the Middlemiss study, which is usually cited by people against sleep training or extinction (CIO): expectingscience.com/2016/04/21/the-middlemiss-study-tells-us-nothing-about-sleep-training-cry-it-out-or-infant-stress/
And here are the authors of some of the studies on child abuse and neglect say that anti-sleep-training people are mis-citing their work: ideas.time.com/2012/05/10/the-science-behind-dr-sears-does-it-stand-up/
A little information on the "cortisol" fear.
"In terms of their effects, the difference between short-term and chronic stress is one not of degree, but of kind. Short-term stress enhances memory; chronic stress impairs it. Short-term stress boosts the immune system; chronic stress weakens it.
So where does that leave us? A little stress, even in infancy, is fine, if not beneficial, but too much for too long is very, very bad.
Do we know exactly where sleep training fits in this spectrum? Just how much stress does a baby experience during cry-it-out?
The short answer is that we don’t know for certain. Everything we do know, however, suggests that this amount of stress, in the context of a warm, loving family, is just fine.
I believe that sleep training is not only not harmful, it is beneficial. Successful sleep training can decrease depression and chronic stress in the parents, and this benefits parents and their babies. Unlike sleep training, having a depressed mother during early childhood has been shown, repeatedly, to be linked with worse long-term outcomes for children."

" To measure the effects on the babies, the researchers did something interesting: they measured the level of cortisol, a stress hormone, in the babies’ saliva. They also asked the mothers about their levels of stress. Twelve months later, they looked for any emotional or behavioral problems in the babies, and they also did testing to see how attached the babies were to their mothers.
Here’s what they found. The babies in the graduated extinction group and the bedtime fading group both fell asleep faster and had less stress than the control group — and not only that, their mothers were less stressed than the control group mothers. Of the three groups, the extinction group babies were less likely to wake up again during the night. And when it came to emotional or behavioral problems, or attachment, all three groups were the same.
This means that it’s okay to let your baby cry a little. It’s not only okay, it may lead to more sleep all around. Which makes everyone happier."
