If you use Android, check out "Distraction-free Instagram". It's an app that lets you disable various parts of the app like your home feed, stories, etc.

I really wanted to stop scrolling on Instagram, but I also really wanted to keep posting my photography, as the interactions I sometimes get on my posts are fun and I enjoy sharing my craft. I also have some friends who ONLY interact via instagram messaging.

I downloaded the app, and disabled everything except messaging, and it's been great. It's definitely made me happier overall.
