Hi all. I don't post often. But I need to vent and I need some support. Please?

I'm TTC my Rainbow, I have had 3 miscarriages in a row. Most recent was 10/10/2016. Well I've been trying for about 4 months. My boyfriend and I want to be parents. Today I found out that my cousin is pregnant with her first baby, she and her husband are so happy. I'm trying so hard to be happy for them but inside my heart I'm screaming and crying. I'm angry. I'm scared. Is there anyone who can help? Anyone? Please and thank you. I'm struggling very severely today.
