What's wrong with me?

Ana • Officially PREGNANT With #3!
It's been almost 2 years since Ive been TTC with one miscarriage. My husbands sister rubbed it in my face when she got pregnant. His sister in law did the same. I feel happy for them but I can't help but feel envious. Sometimes I feel like there is something wrong with me. I break down and cry. My husband tries to keep me motivated and is definitely my shoulder to cry on. He is trying to have me stay positive? But I cant. Im tired of trying. Of getting my hopes up. He wants to get into treatment. We have a 4 year old already. It was so easy to conceive him. Never thought that giving my son a sibling would be so dificult. 😭😭😢😢
