anti fishstick has good advice...especially the "cry when you feel like crying"...there is no shame in that, it doesn't make you a weak person, you need an outlet for grief at times.
I would also suggest getting out and doing things with your good girlfriends...embrace their support and getting out and doing things with "just the girls" will help you take your mind off things.
Do something just for yourself.....go get a kick-ass manicure or go tanning....play tennis or whatever it is that you love to do. Just having some time for yourself away from any pressures will do you a world of good. Enjoy your time and your own company.....remind yourself how good it is to just be you!
Don't be afraid to be sad and remember the good times. Memories are the novels of our lives....one day you may look back and smile and be glad for them.
Hold your head up high and smile and carry on. You have lots of support here if you ever need a cyber hug!
Good luck and quick recovery!
