What the hell happened to me?

HELP!!

The guy got down and put his hands around my neck again started to choke me.
I was facing Jackson so I just kept look at him the whole time.
He started to open his eyes and getting up. Link was already sneakily behind the guy and told me to be quiet 🤫.
He came and tackled the guy while security was behind him and then Jo walked in seeing lots of blood and a gun on the floor. Security was already taking him and locking him way. Jo came running in to help Jackson get up, but saw me turning blue as he left his heavy I.V hanger on my neck making sure I don't breathe.
Jo quickly came in and told link to get me a gurney and took the I.V holder off me and checked my pulse.
It's here but it's very weak she exclaimed.
By that time Jackson got up and saw how my leg was broken again. He grabbed my leg to stabilize it as Link came in with a gurney. Jackson grabbed my back as Jo held my head while Link was holding my leg still so I don't damage myself more. I started to pass out,
I lost her pulse, Book and O.R, Starting C.P.R and get me a crash cart now !! Jo yelled
1,2,3,4,5 - 1,2,3,4,5. CHARGE TO 220, CHARGE AGAIN, 300, ONE MORE TIME CHARGE TO 400
AGAIN 400.
Sinus tachycardia! Link said.
Get her to a O.R right now said Link
I woke up barely,
H-he came b - back fo-for me-e w-with a g-gun and shot m-me t-twi-twice. I whispered quietly
Jackson looked back at me and said I know, but he's gone now and you need to stay with us, ok? Stay with me, Stay for your brother. Alexis your a hero, you saved me so you need to stay with us.
I-I-I can't bre-breathe, I took an deep breathe in not knowing I'd it's my last one.
Jo looked back at me
A-Alexis ? ALEXIS! Can you hear me? Alexis.
Shit, she's seizing SOMEONE PAGE SHEPARD NOW!!! (seizing stoped)
Ok let's go and get a head C.T,
Jackson, Jo and Link ran and cut the line in C.T.
Wilson? Why did you page me it's 4 in the morning.
I'm sorry but the guy came back and attacked Alexis again. We were going up and she started seizing for about 15 second, Scans are up said Jo.
Yup she has lots bleeding and I think that there's a tear in the nerve cells. I need to go in there now or she will be brain dead. Amelia ran to scrub in the O.R. While the scans of my leg we're coming up Meredith came in the room and saw how terrified all 3 of our faces were. What? Why did you all look like you saw a shooter?
Because we saw that and something worse Jackson said.
Meredith was so confused and saw me in the scans.
I-is that Alexis?
