Well, my darling - if you makes you feel any better...I'm seeing this all over the boards today. There must be something in the air.
I've been struggling today, too. No tears, so I feel like I'm gaining ground, but really lonely and sad. It always helps me to go post on other's threads. A lot of the time, when you're not directly in the situation - you can see something a person might be overlooking.
One thing that always works for me is putting a time-limit on how long I'm going to allow myself to be certain way. Say I'm sad? I'll let myself cry for 20-30 minutes, tops. Get it all out. At the end of that time, I dry my tears, get up, and go take a walk or do something else I enjoy.
It's important to allow yourself to feel, while not allowing yourself to completely be consumed by a feeling. This takes a bit of practice, but it is very helpful.
Is there something you want to talk about? Or are you just blue due to the circumstances?
