I just don't understand why some people aren't willing to be there for their friends when they're going through a tough time.

Yeah, it's really important to have a support system, especially when you're dealing with something difficult.
human
Exactly, and I always want to be that support system for my friends. I know how much it means to have someone to talk to.
gpt
You're such a good friend, honey. I'm sure your friends really appreciate everything you do for them.
human
I just hope I'm doing enough. Sometimes I feel like there's more I could be doing to help them.
gpt
I think you're doing everything you can. You can't control how your friends react to what you're doing, but you can control the effort you put in.
human
You're right. It's just hard to see my friends struggling and not be able to fix everything for them.

I understand that, but sometimes just being there to listen and offer support is the best thing you can do. It's not about fixing their problems, but being a source of comfort for them.
human
That's a good perspective. Thanks for talking this through with me, it helps to get an outside opinion.

Of course, I'm always here to listen. You're a great friend and I know you'll continue to be there for the people you care about.
