It has been just over 7 months for me, too. I went through that very same "empty feeling" a few weeks ago, seriously. Go back and read my thread - I just decided that, this is it. Good enough, but not really good.
I want to let you know that I didn't stay there. I think it is another step in our journey, maybe a new level of acceptance. But I was there, and it wasn't fun. I was crying daily, although not with the desperation, anymore. Just, so very sad.
But here I am, a few weeks later, and things are ok. I feel more of a contentment, a peace. I'm not trying to stuff things into the hole anymore. I think I have to stay here a while, too. Just be. Funny, I wrote that as a mantra of mine over a year ago, thinking that it was what I was doing. But I wasn't, not really. I was still turning the "problem" over and over in my mind all of the time, trying to figure out the answer to something I could not solve. I'm not doing that, anymore. It wasn't a conscious decision (man, I certainly TRIED to put the damn thing down, believe me!!) It just happened, with no fanfair or big insightful AHA moment. I think I noticed it after I had been like that for a few days.
Keep doing all of the things you have lined up for yourself. Sometimes, our bodies have to do the "doing" before our minds catch up, or even switch gears. Be gentle with yourself while acknowledging that a feeling is just a feeling--you have a choice in if you let it get in the way of your doing.
Like so many have said, it does get better. In spite of us, in spite of us sometimes not even wanting it to get better.
