@PurplePineapple1 I'm going to be 100% honest here - I know what you're going through, the doctors will tell you to prepare for the worst, which is right, but also don't give up hope, because every case is different.
My husband suffered an aneurysm back in 2014. He collapsed while on a night out with his work colleagues. He was taken to hospital where he was admitted for observation. At 6am, we got a call to say he had taken a turn for the worse, and to come and say goodbye. Three hours later, they opted to transfer him to another hospital with a specialist neurology department, with a plan to operate to clip the bleeding artery. The operation was successful, but within 48 hours, his brain had swollen to the extent of his needing a craniotomy - removal of part of his skull to enable the brain to swell freely until it subsided.
The next 48hrs were touch and go, with the doctors constantly telling us that due to the size of the haemorrhage, it was unlikely he'd pull through, and if he did, he would very likely be left in a vegetative state. at worst, or completely paralysed with cognitive deficiencies, at best. Around two days later, he was responding to external stimuli, such as touch, on the left side of his body. He wouldn't respond to commands from doctors and nurses, such as hand squeezing, only when I told him to! After less than a week, he was transferred to the high dependancy unit, two weeks later he was transferred to a general ward in another hospital whilst we waited for a bed to become available in a physio unit.
I'm not going to pretend everything was rosy; he was left with deficits on his right side, had issues communicating for around six months, and had both long and short term memory loss. He had another two mini strokes when they replaced his skull with a titanium plate six months after his collapse, but he defied the odds, and although not the same man as he was, there were flashes every now again of his humour and personality, and we were grateful to have him back for the four more years he was with us.
Don't give up hope, but also remember to rest - easier said than done, I know, but you have to look after yourself to be able to advocate for him. The night I left him at the hospital for his plate operation, I got home, and literally couldn't move for two days - my body totally shut down on me, very likely because it knew I needed a break, even if it was a forced one.
Assuming you have a strong network, don't be afraid to ask for and accept help from your friends and family. You may think this all on you, but it doesn't need to be.
