Freckles, who's to say what's normal? The fact that your longing has intensified is probably a clue as to what else is lurking in your psyche.
I can really relate to what you describe because I am going through something similar. I feel a bit sheepish writing this, but what the hell, here goes. I'm anonymous after all
I dated a girl at work briefly, after a few months of an emotional affair. One month later, I got severely depressed and ended it. We stayed friends for the next year, emailing each other daily. She is about to leave work for good on Friday and I have been devastated. I cried so hard I gave myself a headache for 3 days. For the past year, I've missed our closeness and that's been extremely difficult of itself.
Like you, I've done a lot of journalling, discussed it with my therapist, tried to distract myself. Nothing would budge it. But I started to realise that this intense pain was a clue I needed to examine. I started to realise that every time someone close to me left my life, I felt intense pain, anxiety and longing. I also came to realise that all these episodes were linked in time, and that they all felt very similar. I started to speculate that maybe I was reliving a version of my first abandonment each time (my first abandonment was when my father left when I was 7).
With that in mind, I did an exercise with a close friend. I got back into that emotional space - the intense longing for my work colleague - and I tried to experience the full intensity of it. I then tried to recall how I felt as a child when Dad left. Then my friend role-played my Dad, and through my intense sobbing, I asked "him" why he left me and told "him" how much I missed him (my Dad died a few years ago btw). We did that for about 10 minutes.
I know how freaky that sounds, but it actually made me feel a lot better. I felt a release of sorts, and I didn't cry once today, not even close. I'm still sad and I miss her already, but it's plain sadness without all the desperation. I did the same exercise for my friend a couple of weeks ago, and it was very powerful.
I don't know if that helps you or not, but you may discover that there is a lot more going on with your pain than meets the eye. And as you can see from my example, pain can be your friend.
