How do I get through this. I lay next to my 15 year old daughter as she gasped her last breaths and died. 9 months treatment for a cardiac sarcoma. Open heart surgery, gruelling chemo and then during her 6 weeks proton beam therapy she developed 3 aggressive brain tumours and died 3 weeks later. We had her home for 3 weeks palliative care after she developed left side paralysis as the tumour was so big. I can't get to sleep tonight as rel-living the sound of her gasping to breath as she lost the ability to swallow. There doesn't seem to be anyone who understands the loss of a teenager full of life and dreams. How do I get through? How does my family function without her?
