Frustrated

R
My husband and I have been trying for a baby for over a year and a half. We had a heartbreaking time, for numerous reasons. It was very rough. 
I have a "friend" who started trying about 3 months ago. She did nothing but complain about how hard of a time she was having and how frustrated she was. Without any regards to my feelings at all. 
I found out a couple of weeks ago that I am pregnant. I am now 8 weeks and 2 days along. I chose not to tell this friend as I didn't want to cause her more discouragement. She told me over the weekend that she is 6 weeks along. 
She didn't know that I was pregnant, but told me and didn't seem to care about all of my struggles getting pregnant. I have since told her, and she doesn't act like she cares at all. 
There must be more people out there who are having something similar happen? I feel like I'm not excited anymore because she won't stop flaunting it every second of the day! I thought we were friends but she doesn't care about being sensitive to me in the slightest. 
I am excited for them, I know she's excited to, but I'm struggling...
We are planning to announce at Christmas to our families (my husband and I), and now she's going to announce then too. I just feel like my excitement is gone. 
Please help me see it differently so I can be happy again!
