Dealing with friends that are pregnant and have children

How do you deal with friends saying that they know you are sad and upset and can't begin to understand your journey and pain of ttc but in the same breathe are upset that you are not excited for them and not supportive enough of their pregnancy. Friends feel like there are scared to talk to you in case they might upset you. They feel like they can't talk about their babies in front of you and are upset with you for not showing enough interest in their babies and pregnancies. For me it is self preservation and a coping mechanism to not want to be around them and talk to them about their pregnancies liking every single photo of their baby on Instagram. Feel so vulnerable and now hey coming down on me for not being involved enough!
