Thinking I’m Depressed

I had a miscarriage recently and I thought I was finally moving forward with myself and everything. I have a few family meme era that are about to have their babies and obviously I am beyond excited and happy for them. But as the time approaches for them to have them and I see more and more posts on social media I can’t help but feel extremely sad and upset. I feel like no one will understand what I’m feeling because I am angry with myself for feeling this way and not quite sure why I am so upset. I have this deep overwhelming feeling like it’s just never going to happen for me and it’s seriously crushing me. I am not a sad or depressed person, I am constantly being the life of the party and trying to make sure everyone is having a good time but I cant even force myself out of bed sometimes. I want to be supportive and I want to be there for them but I just feel like I am going to be a burden for everyone else and I really don’t know how I am going to react at this point. My emotions are just uncontrollable and all over the place right now. I just wish I could move forward.
