This is gonna sound silly, but feeding the local birds is really therapeutical. For the span of a moment it's not about you, it's about the simplicity of feeding an animal you don't know, that will likely not care if you come back. No strings attached.
I used to wonder why old people do that, now I get it. It just feels nice.
A word of advice though if you plan on doing that, look up what you should and should not feed wild animals. Bread is supposedly terrible for ducks. And crows will go crazy about peanuts. Funny to see them crack them open too.
