Coping with miscarriage and find out about accidental pregnancy with friends

Danielle
It's been a rough few days my hubby and I have been TTC for 6 cycles got BFP last cycle and miscarried at 6 weeks....no friends that understand it because they have never experienced it I'm having a very difficult time being happy for a couple we know who got pregnant on accident....I'm so angry! I hate feeling this way just sad and angry :-( and thoughts or suggestions ?
