All my life I've had a great body and been in shape I wasn't so thick but not so skinny either. Last year I became pregnant and since the first month pregnancy symptoms were so horrible on my health and body that I reached a point where I could see my bones in the mirror while naked. It sadden me and made me extremely depressed. Ofcourse there's always people and those who always have something not nice to say and through my whole pregnancy I had people continuously telling me I looked sick and that I needed to eat and how awful I looked etc. I kept my pregnancy a secret until my very last weeks because I just had so much going on besides people ALWAYS saying negative things about my body that it traumatized me to the point I can't even look at myself in the mirror anymore. I'm 3 weeks pp and I feel worst. When I was 2weeks pp (last week) I had pp hemorrhage, I was at the edge of my life because I lost more then half of my blood, I almost didn't make it but god is big and I also had incredible doctors who did everything to save my life, and I'm here telling you all about how I feel and what I've been through... 
Knowing that I was dying has really changed my whole life besides my baby(FTM) whom I'm in love with👩‍👦♥️
I want to change my life to be one where I am happy and where I love myself and my body as well, I want to feel confident again. I'm desperate for that! 
I always see so many things to help loose weight and I don't ever see stuff to help gain weight or maybe I'm not well informed.. 
but a lot of people think it's so easy to gain weight which I think it's not for some people like myself lately.. 
I feel like just as hard as it is to loose weight for some, it's the same for some to gain..
I would really love to know if there's anything that helps with weight gaining and I also would love to know stories of anyone who's ever felt or been through what I been through regarding their weight and what you have done to over come your situation. 
Love to all♥️♥️♥️
