Having trouble coping with miscarriage

Kate • mommy to a little boy 4/30/18 💙👶
I had a miscarriage almost a year ago.. I don't know if anyone else has gone through this.. After the incident, a lot of my friends and family had babies and it was very exciting.. I'm happy for them but at the same time, I feel left out because I should have had my baby around that time too.. In a few weeks a family friend is having a surprise baby shower and I don't know if I should go or not.. I want to support her but at the same time I don't want to be a crying mess when I get home.. I have my good days and bad days but I'm really trying to deal with it the best way I can.. Any advice??
