We lost our only daughter 1 year ago, I have severe upper back pain, head ache,memory loss and difficultly breathing?

I am 28yr old. We lost our only daughter 1 year ago, she was our only hope and purpose of living, and our life. She was only 5.11yr old. She had viral fever, after few medical tests, medicines and treatment it became normal and suddenly at night she passed away within few seconds. We couldn’t do anything. Since then we lost our hope and belief on every thing and everyone. Few months ago we expected the same baby but it got abortion with no reason. Then had surgery for cleaning and complete abortion. Since then we completely lost trust and hope on life. Since then I feel weak in my palm and feet, I feel swelling and difficult to close fist and pain. I feel difficulty in breathing, I can’t breathe like before. Sometimes at night I feel so hard to breathe like going to die. I have severe upper back pain, head ache. And memory loss. Sometimes can’t remember about the breakfast which I ate. Can’t do any work. Digestion problem. Lot of confusion. No trust on anyone. Sometimes I feel like slight shock in chest and can’t breathe or move for sometime, it’ll be painful. I feel my entire body weak. What do I do?
