Also just FYI regarding the injury, we aren't talking about a serious broken or even sprained ankle. She snowboarded on it all day and she snowboarded on it the day after and everyday after that. She was back up and walking around on it and out in the slopes the next morning after our fight.
You are right about anxiety. It's not a defect. I myself suffer from anxiety. And yes, those who love you should care and try to accommodate and ease your anxiety. But it's not all other people's responsibility. It's not up to others to tiptoe around you so as not upset you. You also have to be personally responsible for managing your own anxiety to a reasonable level, to ensure you're not letting it hurt those who you love.
She wasn't asking you to do anything. She was sleeping. She didn't ask to be woken up, gotten out of bed, etc.
There was nothing that important that she had to get up.
Her pain is not your pain, or anyone elses. Sometimes you recover quickly, other times not.
As far a being "responsible", no, it's about being kind. I don't tiptoe around someone who's hurting, but I certainly don't bother them. I make myself available.
Her anxiety flared when you woke her up and got her out of bed. Before that, she was anxious, but did handle it herself by separating herself from others and taking a nap.
You two probably weren't right for each other, and she made the decision to move on, as you should.
However, that night could have gone very differently if you had let her sleep and brought her some soup or a sandwich for when she woke up.
Anyway, where was all this "gladly" helping her? Your parents took offense, I have no idea over what, you woke her up, stayed in the room because you felt guilty.
Oh, you brought her some tylonol or something, there is that.
If you also have anxiety, look at your part of rushing into the room, and going from there. She too wasn't responsible for walking on egg shells because you thought she needed to get out of bed and get herself down to the dining room.
Just understand your part in this, never mind hers, she's gone, and move on.
