Dealing with pregnant friends

I just had my second miscarriage this yeat. One in march with a blighted ovum and the pills to induce miscarriage and one the begging of November that was a tubal pregnancy where I had a dnc and the methotrexate shot. I am so damn frustrated and sad and you never think this thing will happen to you and it does and then you think no possible way a second time and it does. When the words fertility docters after 3 miscarriages comes from your docters mouth, it's like your world stops. So then I go to dinner with my best friend who had a miscarriage around the time I had my first one and she tells me she is pregnant. Had her first ultrasound today with a strong heartbeat at 8 weeks. I try so hard to be happy and it just rips me apart. I'm really struggling to not be bitter buy man, anyone else get like this? ?
