Jealousey??

So idk im so sad so depressed. A few weeks ago after years of trying I had a chemical pregnancy at 6 weeks 3 days. A week after I finished bleeding my brother and sister in law tell me they are expecting baby number two. I clapped congratulated them but went to the bathroom and about cried before my 2 year old niece came in so i couldn't cry in front of her. It was sooo hard. Yes they knew I lost my baby. When i told them i was pregnant they stressed me out ganged up on me about how i need to break up with my boyfriend then when i told them i was pregnant hoping they would stop for now they switched from me breaking up with him to getting him to step up which he is he's growing up got a job paying bills etc. They felt bad for saying anything when i went to the bathroom and they shouldn't, they should be happy and im happy for them im just really sad for me. If that makes sense.
