I feel so sad

my best friend who got married in January just told me shes pregnant I've been trying for 3 years and now need ivf. When she got married she said she was guna wait for abit but she decided not to.. She wants to see me and tell me personally but I cannot face it. She knows I'm struggling to conceive for past 3years I am happy for her but should I avoid her.. Cus right now I dnt want to see her and is that normal to feel like this?
