Louise, I also experience similar things. Sometimes I wake up in the middle of the night, and my brain is thinking so hard that I'm having trouble breathing and my heart is racing. In September 2020, I lost my friend Josie. She also loved to write in her diary. When she left us, my symptoms got worse. After 10 months and several other hardships, I decided to ask for help. I was diagnosed with post-traumatic stress disorder, which changed everything for me. I was finally able to understand what I was going through. Without knowing it, it had been there for much longer than I thought. The symptoms were so intense and present in my daily life that I thought it was the norm. It is still challenging to learn to live with it today, but I feel better equipped. I know myself better, and above all, I can notice when I am not feeling well. For example, when the dishes start to pile up... It helps me a lot. If I could have read the words of someone going through the same thing as me, it would have made a big difference. So thank you for sharing what you are going through! It reminds me of my friend Josie, which makes me feel good.
