EVERYONE BUT ME πŸ˜“πŸ˜“πŸ˜“

I hate saying this I don't mean to sound like a bitch but it's so hard to be happy for people sometimes when they have everything you want and they got it so easily and you've been trying so so hard and nothing is working :(Β 
My best friend is 30+ weeks pregnant and I am happy for her but there is a part of me that's jealous/sad/angry that it's not me.Β 
To top it all off I just found out my younger sister is pregnant too and she has only been dating her boyfriend for a couple of months, doesn't have a job and still lives with our parents. I am happy for her too but it just sucks so much that the people that try the hardest sometimes never seem to get what they want :( 😒
Am I the only one that feels like this?Β 
I'm sorry if this offends anyone it's not my intention.Β
