Dear Daniel,
Here's my two cents, based on personal experience.
I've read your posts, and what your turning out right now, as far as your writing, is absolutely beautiful, stunning, heartfelt, and yearning. I KNOW it's coming from pain, but it doesn't make your writing--how you are interpreting what is happening to you--any less beautiful. Marvelous stuff. Hope that doesn't sound cold.
I was unhappily in love a few years ago. I'll spare the details. But what I did was pour my heart out into my journals, letters to friends, etc. It didn't FEEL like it was helping much at the time, but it DID help. And now I can look back on all that writing (I saved it all) and think, "Wow, what an experience. I'm glad I documented it." And document it I did. Every glance, every imagining, every dream, every conversation.
Keep pouring it out, Daniel. We're reading and comiserating.
