Tam, I'm back for more. My comments may be totally useless to you, but on the off chance they are helpful, here you go:
I just looked at your website and saw that you recently got a bike and went to a yoga class. So you have great exercise options that could be really helpful. I've found that yoga and meditation can be an enormous aid during painful times.
It might help to think about ways to indulge yourself. Would you like to go get a massage? Get a mini-makeover? Take an afternoon to just lie around and watch TV? Anything that lets you pamper yourself could be good.
Sometimes it can help to just throw yourself into work and not think about it. If you want to do that, that's fine too.
One other thing to think about: our culture tends to put a huge emphasis on how long relationships last, but a relationship doesn't have to last forever to be good. There's such a romanticized picture of finding your soul mate and riding off into the sunset together...so then people can feel like failures when a relationship ends. You think oh, I must have done something wrong. But even if a relationship doesn't last a lifetime, you can still get a huge amount out of it. Did you learn from your relationship? Did you grow because of it? I bet you did, and therefore it was a successful relationship. And you'll continue to have wonderful relationships in the future - with work colleagues and friends as well as with romantic partners - that will reward you as a person, help you learn things, and help you grow even if they aren't life long.
Like Angie says, we're here for you. Let us know how to help.
