Misscarige

I would be 5 months today, I never thought a misscarige would be so depressing 5 months on, I thought I would get over it by now. Whenever a baby smiles at me on the street or waves at me I break down. I feel guilty to think that I was so happy that I found out I wasn't pregnant anymore and never wanted my child. It's now breaking me. (I found out I was pregnant the day before my 18th birthday) I feel like I'm not allowed to be upset about it and I have no one to talk to because they don't understand, they all think I was stupid for wanted to keep it. After all I was 17. I do baby sitting as a job and it breaks me to think I would have had my own little family in a few months time. I don't know how to deal with the pain. I just feel so stupid to even be upset about this.
