@speakout that sounds really tough. I can relate as I know what it was like when my Grandma was in hospital for two weeks. It takes over everything. When you're not physically at the hospital, you're thinking about the situation, discussing it all with family, etc. I found I was not eating properly as I was too tired to cook when I got home, and I got very run down.
If you can, try and prioritise meeting your basic needs - food, water and sleep. Healthy snacks like bananas, yogurts, granola bars and things that are easy to make, baked beans, scrambled eggs, soup, etc. Try and keep hydrated, hospitals are so hot, I found I was getting dehydrated which gave me headaches - remember to pack a big bottle of water when you go to the hospital. Sleep is the hardest bit, as I'm sure your mind is buzzing, and you're worried and waiting for the phone to go in the middle of the night. I found having a warm shower when I got home helped and using sleep music/ sleep stories.
I think that being afraid to speak up is possibly a generational thing. My Grandma was unable to speak up and my parents were afraid to, so I had to take that role. The majority of NHS staff are great, but some are really lacking in understanding and empathy. I find the hospital environment incredibly stressful, it's so noisy and not really conducive to recovery.
Sending you love and solidarity xx
