My brother-in-law was diagnosed with advanced Bowel cancer at Christmas. He passed 3 months later. we supported with his homecare, and we were with him when he passed. Seeing him in so much pain and he ended up with a full blockage so was vomiting a lot in the final days. This escalated until he had to be put into a sedative state and passed the next day. Ever since, sleep has been difficult. I have been having nightmares, been feeling extremely low at point and had several moments where I have just wanted to be alone. It's difficult to know how much time to allow before seeing a GP. It's only been a couple of weeks, but the more time passes the worse it gets. I woke up last night and cried, my mind was so dark and I felt this huge sense of worthlessness. Guilt seemed to surface at night after have a day of what seems like feeling better.
