Bones, I wanted to speak to your feelings of desperation and hopelessness. I've felt that way. Many times. I don't know if it will help you, but here is what worked for me: stubbornness, and the realization that if I gave up, the no-goodniks won. I just refused to let the no-goodniks win. Not at my expense, not that way.
Again, I don't know if this will help you at all, but consider... even the simple act of continuing to draw breath is a form of defiance, a gesture at Fate, at a time like this... even the simple act of getting a good night's sleep. Of waking tomorrow and having a cup of coffee [or herbal tea] out on the porch in the sun.
Of holding your boyfriend close.
You've given a lot here. You have a lot that is worthwhile to give, and you deserve to receive a lot of good things too. This setback could be a turning point. But it's too soon to try to make anything be or happen now... be good to yourself, and remember: merely continuing to be - here, as yourself - IS an accomplishment. Nobody else but you can do that. Nobody else but you.
