She's not alone. Most of us have lost people. Everyone who shows up vanishes, and it makes it very difficult to form new connections. To find support.

I understand. I'll be nicer to her.

I'm not proud of the fact that I withdrew from her, but I'd rather give her space than let my hurt feelings get the better of me and attack someone for caring when I never got that...

You're lucky to have family who cares. Who's here. She ought to be cherished...

Do you know that your nonchalance, that stone-faced attitude you have makes it seem like you don't care about anyone? Acting or not, you're aware how others may interpret it, right? That it may make things more difficult for you going forward?
