Am I a terrible person ?

I've had 2 ectopics in the last 3 years and unsuccessfully gotten pregnant since the last one which was in June 2015. My impatient, selfish sister who never wanted kids and still didnt want any kids til after i lost the second one..She doesn't even associate with her nieces and nephews and is also in an abusive relationship has just recently given birth to a little girl. I haven't seen her and haven't even spoke to my sister to congratulate her. I just feel like this child is going to have a terrible upbringing then me on the other hand has a good relationship, a house, a good job and I can't get pregnant. I know im going to sound jealous and bitter but I honestly don't wanna see her or the baby I really do feel like she got pregnant to rub it in my face like everything else she has done all my life!! I just don't know what to do as my family are on my back to go and see them, I know it's not my nieces fault but I find it so difficult to be around babies!! Please don't judge me for saying these things. I just want some advice on what I should do??
