I'll only write what i have experienced, so, here we go:

 It is so easy to get out and make a fool out of yourself and your body when you're heart broken. And yes, i have been there. I got severely drunk and although i was with a friend, i ended up getting a bruise from a glass bottle that was thrown across a fight and me blindly walking right in the middle of it. I still have the scar right in the middle of my back. So, getting back to your question...

I've read the other answers to this request and i have to say, although being around friends and family is definately a good and healthy idea, SOME isolation does do you good. It gives you time to think, and it gives you time to truely appreciate yourself as an individual. Especially if you're recovering from a long-term relationship where you couldn't imagine yourself without your other half and when day-to-day things were done in synchrony with your partner. Of course you may not have the patients to read a book and call this mind easing...you need a quick "fix" to remedy your heart. So!

The best way i suggest is to splurge. It sounds shallow but it should work. Spend a week or two, depending on the rate of your expenditure- go shopping and buy that piece of clothing or shoes that you've always wanted. Get a facial and any other spa treatments that you can afford. Get your make-up done and make yourself feel glamorous. Remember this is about you and nobody else!

When you have done this you may now spoil yourself with wine and chocolate or similar with close friends. It is wise to spend a few nights with a girlfriend as you may feel most vulnerable at nights when you go to bed. Also, if you have a pet like me, now is the time to take him/her everywhere you go where possible. For example, i took my dog to the supermarket and even to my university when i had a couple of classes so i could take him out for a walk in the park in between lessons. He will listen to anything you have to say and he will definately notice when you are weeping! Definate companionship even when all your friends and family are busy!

Ok i think thats about it. Remember, don't go for the alcohol unless you are in a safe environment (e.g. wine with girlfriends at your house), take time alone to pamper yourself, have night-ins with your close ones, be even closer to your pet and oh, i almost forgot- get rid of everything that reminds you of him- sell it if you have to ;)
