I'm going to share my food
That's nice. Why did you decide to share your food?
It's just something I felt like doing for a while
That's very kind of you!  Sharing is caring, as they say.  I hope whomever you share with appreciates it!
I think it will all be fine.
I think everything will be fine too. I am glad that people like you still exist and I do hope everyone strives to share what they have so people will feel like there are still a lot of friendly people out there, specially with all the things that are going on in our society today.
