I'm so glad I could help even a little.
So your support network is in another state--e-mail them! If I can help (and I'm prolly in another state) please let me know. I'm prolly old enough to be your mom (as indicated by the date of breakup of my "first love") but not having any children (except four cats) I can't offer any motherly advice. Like I said, force yourself to go out and do something, try something you've always wanted to do and you might make some new friends.
You have one big thing going for you and that's that your family seems to be supportive. You will have to go through this solo but I'm at least here and will be happy to be a shoulder to cry on.
This song came out before your time but Gloria Gaynor did a disco (yuck!) song called "I Will Survive". Here are the lyrics:
First I was afraid
I was petrified
Kept thinking I could never live
without you by my side
But I spent so many nights
thinking how you did me wrong
I grew strong
I learned how to carry on
and so you're back
from outer space
I just walked in to find you here
with that sad look upon your face
I should have changed my stupid lock
I should have made you leave your key
If I had known for just one second
you'd be back to bother me
Go on now go walk out the door
just turn around now
'cause you're not welcome anymore
weren't you the one who tried to hurt me with goodbye
you think I'd crumble
you think I'd lay down and die
Oh no, not I
I will survive
as long as i know how to love
I know I will stay alive
I've got all my life to live
I've got all my love to give
and I'll survive
I will survive
It took all the strength I had
not to fall apart
kept trying hard to mend
the pieces of my broken heart
and I spent oh so many nights
just feeling sorry for myself
I used to cry
Now I hold my head up high
and you see me
somebody new
I'm not that chained up little person
still in love with you
and so you felt like dropping in
and just expect me to be free
now I'm saving all my loving
for someone who's loving me
I played this song over and over and dreamed about the day this would happen to me. It did, in time.
If there's a funny part to this, a few months later "he" called me at work asking me how we would handle things if we ever saw each other on the street. I was so lucky I had a chair nearby because my knees buckled. I was so stunned to hear his voice that the first thing I asked him (in an astonished and slightly annoyed voice) why he was calling me to ask me something like this. I said that we'd have to deal with that when the time came and I think I said good-bye and that was that.
The secretary that was sitting there said he was trying to get back with me. The was no way on God's green earth that I would ever consider getting back with someone who was such a manipulative person.

I couldn't believe I said that and I knew then that I was on the path to healing.
You will heal in time and it may take until after she leaves. Then "clean house". Get rid of anything that evokes strong memories, or at least rearrange your furniture (that could be cheaper). Get some new wall decorations that reflect who you are. In fact, why not do that now? She doesn't like it, too freaking bad. Assert yourself (you may have to cry privately) but if you can show her that her leaving is just another thing in your life, like cooking a meal or washing your hair.
One of my problems is that I'm a problem-solver and I'm really great at telling people how to live their lives when my own house isn't in order (I have a very special friend who is coping with depression and it's killing me that I can't take his pain away and carry it myself). But in your case I can give you the benefit of my experience.
Do you have enough money to afford another move? You could at least get some empty moving boxes and make it look like you're moving. Give her vague answers if she asks. Sounds like you have no ties to her and a new start may help. At least get your phone number changed and have it "unlisted" and "unpublished". It costs a little more but she'd never be able to call you and mess with your head. Even though I'm a woman I can be extremely unforgiving to my sex when it comes to things like this.
Today is a new day and one day closer until she leaves. How about a calendar with the day she moves circled in some color and "X"ing out each day before she leaves? She wouldn't like that and you might be surprised how much better (incrementally) you may feel. Two months looking ahead seems like an eternity but look how fast the last two months went.
When she goes, reward yourself with something--throw an "I'm free" party, buy yourself a nice toy, rent a DVD that you've always wanted to see, JUST DO SOMETHING! Having survived something like this you deserve something good.
With good wishes,
Camille
P.S. As far as Clapton, I'm still waiting to return my calls
