Venting

I have a cousin who married later than me and got pregnant soon. We have been trying actively for 2 years but no luck so far. Recently she celebrated her baby bday. I was like all down already but I am happy for her. No one understands my pain n what I am going through. And each and everyone one asking why I am not trying to get pregnant and all. It just hurts a lot. Now my cousin she is like with attitude of she got pregnant and I couldn't and that itself hurts so much. She doesn't share any info of her baby with me like I would be jealous or something. This makes me hate her more. I don't know what to think or do anymore. Just hate all family members. Even friends could understand the pain but relative they all are... Couldn't use words.
