When did it all go so wrong? (Up for adoption)

Part 6

So I don't know why I am telling you this but I am. Marks suicide letter in this is not the one I wrote for my friends and family it's very similar (I changed some names and added some things.) Anyway... As if this chapter doesn't give you enough feels I for some stupid reason decided to add that piece of info.
This chapter is for septipliertrash101, who has been showing there support for the story. I really appreciate it so thank you so much.

"Where is she!?!" Felix said starting to panic.
It has been about 2 hours and she still isn't back. And Felix couldn't call her because she left her phone
"Let's just walk over there. I bet she is just talking with Mark and lost track of time." I said.
Everyone agreed that was a good idea and we payed the bill before walking to the hotel.
To our surprise Marks room was completely empty, as was Felix and Marzias.
"Where could they be...?" Felix asked, his voice shaking badly.
I hugged him.
"I don't know... But she is okay." I said, ignoring the horrible feeling in my gut.
After convincing Felix to go to sleep and that she will be back tomorrow we all went to our rooms. I didn't sleep though. I thought about Mark. He looked so broken when I left.
And even though the sound of him crying was haunting my thoughts I did manage to drift to sleep.

...In the morning...

I woke up and walked over to Felixs room after changing and putting a beanie on my messy hair.
"Hey buddy... Any word from her yet?" I asked sitting beside him on the couch.
We went out to breakfast when Felixs phone started ringing.
"Hello?" He asked
"Marzia! Where are you!?! I've been worried sick!"
"What!?! Why?!?"
"MARZIA ANSWER ME!" He shouted, earning us a few confused looks.
He slammed some money on the table and started towards the car. We all ran after him.
"What's wrong!?! Where is she?" I asked.
"She said she is at Sacred Heart hospital (references!) but she didn't say why?" He said frustrated. We all drove there quickly as we could.
"We are here to see Marzia Bisognin" Felix said to the person at the desk.
"There is no one here by that name." He said.
Everyone looked confused when something hit me like a bus.
"Mark Fischbach?" I said.
"Mark isn't allowed to have any visitors due to his current state. But there is a girl waiting outside his room. I can lead you there." He said.
I nodded, feeling anxious and Panicked.
'His current state...'
What happened to him...
We saw Marzia crying in a small plastic chair and Felix ran over to her, gathering her into his arms and kissing her head.
We all got a group hug.
"What... What happened?" I asked.
She started crying.
"I found Mark... In the tub... He was covered in cuts all over his arms. There was an empty pill bottle and vodka... There was blood everywhere Felix..." She said sobbing into his chest.
"Mark... Mark tried to kill himself...?" Felix said pulling away to look her in the eyes.
She nodded and handed me a letter.
(Jacks thoughts/ actions are in bold)
"It is for all of you..." She said.

'To the friends I call my family,

By the time you read this letter, I will be only a faded memory.

A corpse on the cold bathroom floor.
Tears started falling faster.

It is too late for me now, and I know it.

Even as I write this letter I can feel the life draining out of me.
'This has to be a dream... Mark... Mark can't die...'

But I feel it, so that's something, right?

I have been dead for a while now, though you may not have noticed.
'How...? How did we not notice...?'
