I'm too young for this 😥

I just turned 16 and had a miscarriage at the end of last January when I was still 15. I know it's been awhile since then but I still cry about it all the time. I want to talk with my boyfriend about it but I don't know what to say. I just end up crying and hugging him. I didn't want a baby but I told myself that I might as well make the best of it. My boyfriend and I started looking at baby room ideas and clothes and just preparing and then it was gone. The only people who know is my boyfriend, doctor, and my best friend. I don't know how to talk about this. I don't know what to say. I don't know how to get myself to stop crying
