This is so stupid why I am I like this

I told a new hairdresser I was pregnant when I was only 5 weeks. I had a miscarriage. I went to my appointment today hoping she would have forgotten I mentioned it. Was even going to cancel the appointment. Well I get here and she asked about it and said she herself was pregnant. I told her I lost my baby and she said “oh no” etc etc. but I am just so fucking angry. Why does she get to keep her baby and I don’t? Now I have to sit here for 2 hours trying not to cry and trying not to hate an innocent woman and her baby. This is so fucking unfair. I hate this. When does this stop?!
