Am I Crazy For Being Mad??????

Ok well you all know that I am 16 and I have a little girl named savannah.
Well when I told my parents that I was pregnant, they didn't act so well. Now my 17 year old step sister, who lives on the streets of ottawa got pregnant by a 24 year old that she is not even dating, she told them just the other day that she is 3 months pregnant and they reacted great, they were all happy, and hugging her and saying congrats, meanwhile I am standing there with savannah in my arms thinking thats not fair, ya I got pregnant when I was 15 had her when I was 16, but I had her with a guy that is my age, I don't live on the street either, and yet when I told them that I was pregnant they acted like had let them down in so many ways, and yes I did, but at least I can take care of my baby, with andrew to help me. My sister lives on the street, and the guy that got her pregnant was like oh I want to be your boyfriend, and I want to help you with the baby, but as soon as one of my sisters friends show up he's like I don't want to be with you anymore, and he tries to get with her friend. Oh and to top that off my parents decided that they should celebrate,they decided that we would go bowling, not out to supper that way I could go too, no so I had to stay home with savannah, while they all went out bowling. Am I crazy for being mad???
