Mother's Day Loss

Tori
It will be exactly one year on May 12th that I lost my first pregnancy. I was 8 weeks 3 days, and it was the worst time of my life. My boyfriend and I celebrated Mother's Day early last year, because he was working on the actual day. I still have my flowers and card he bought me. 
People that I've spoken with about Mother's Day, say I should still celebrate it; because I was once and will always be a mother to a baby in heaven. It's such a bittersweet feeling. I want to celebrate for my mother and my sister and my boyfriends mom. I'm just not sure if I should be celebrated. 
It's not something one usually thinks about after they've lost their child. Getting through this has been a struggle, even a year later; I still feel like it was yesterday. 
What do you think? Should I celebrate and want to be celebrated on Mother's Day? Please let me know what you think, or what other way you celebrated instead.
