Yup, that's why I said "otherwise one hasn't gone all the way". I'm not denying your struggles, just telling you that there's still more to come for you and that you don't need to assume that "that's it, now I got it".
The reason why you ultimately can't separate truth from happiness is because truth is not something we need to "accept" (ultimately). And if it is, it means that there's resistance to it. And if there's resistance to it, it means that there's still some breathing room for dualities, subtle as they may be.
Truth is so absolute that it will not leave you any room for doubt or "not accepting". You understand what I mean?
Your struggles mean one of two things, either:
1) you are deluded and are now suffering because of it - which is literally the number one reason for suffering in general;
- ignorance (i.e. "not being consicous of something")
- (false) beliefs, however convincing they may seem.
or
2) you have indeed realized the Truth, but only partially: and we're back again at point 1) , ignorance. You're still ignoring something.
In either case, humility is your best friend. Entertain both possilities separately and do not favour one over the other.
