You can always DB, it's just difficult to DB *well* without patience. Being impatient, having expectations, getting emotional because you don't feel you are seeing enough success, etc... will create backslides, tension, and emotional situations.
You don't need to pretend life is awesome, you just need to not be a downer because that won't be attractive to her or anyone else for that matter. You need to try and find things that make you happy (things that don't have to do with her) and try to find things in your life you are thankful for and that you appreciate so the world and your happiness isn't focused on this one other person. In other words, you have to detach. I think that's your biggest hurdle. But, it sounds like you don't want to detach.
Well, it's still very early in your situation. I don't know if you've read the book, but my advice is read it, reread it, reread it, reread it....etc...
There is no arriving, ever. It is all a continual becoming.
