It's natural to try and avoid suffering, still acceptance isn't a way of escaping what you're currently going through, if anything it's to face whatever is arising so that you can process it accordingly. The idea that through doing something called 'letting go' you'll be better off is only holding onto a future that doesn't exist.

Just Be isn't really an advice to do something, it's like suggesting to Be Still... anything you try to do isn't being still but another movement happening in the Stillness, just like you can't do Awareness as it's already present. So it's more of a call to stop thinking with your mind so much and remain as Awareness, where you aren't trying to get somewhere other than being here/where you are.

Jees (as usual) has a great approach... don't know how, knowing is closed, stay open, stay as the unknown.
