Am I wrong?

Last year I had to have one of my ovaries removed and the doctor told me that I will probably have to have the other one removed in 5-10 years( I'm only 26) My cousin just had a baby on 7/18/18. She has openly talk about how she didn't want to have this baby ( the baby interfered with her travel plans and how she can't wait to get back to drinking) I went to visit her today and as I was buying her balloons I became overwhelmed with emotions. I collected myself and went in there to visit her and the baby. As I watched her trying to breast feed the baby I could feel myself begin to cry again so I made up some excuse to leave. I cried the entire way home. I also just found out that her sister an unemployed 21 year old high school drop out is pregnant. I cried at the news my family says I'm just being miserable but they know what I went through with my surgery they know that I have had baby names picked out since elementary school. Am I wrong for feeling this way?
