<human>: Can you condense the text into three sentences or less?

I'm going to sound like a huge bitch here but hear me out. I'm writing this from a hospital.

My MIL was diagnosed with stage IIIB breast cancer last year, she did the chemo and now she's 100% cancer free. Today she had a single mastectomy and me and my SO and his 16 year old sister are all in the hospital keeping her company.

She has to stay in the hospital overnight and without even asking us, she mentioned us all sleeping in her hospital room tonight. There is no extra bed or even a couch so we all have to sleep on reclining chairs tonight.

This seems like overkill that she wants us ALL to stay but I understand that she needs support but I just got off a plane this morning (was visiting family in another state) and I've had ZERO sleep and now I have to sleep in a hospital room on a chair. I just want to go home!

I wonder what would have happened if even MORE people were here keeping her company, she'd probably have people sleeping on the floor! There is NO room in this tiny room, they even had to bring in 2 extra chairs for us to sleep on.

Am I being a huge bitch? I don't want to tell her "No sorry I'm not staying here".
<bot>: MIL is in the hospital overnight following a single mastectomy, insists everyone sleep overnight in the hospital with her without even asking us but it's too rude to say no.
