Advice on a Friend

What do I do and has anyone dealt with this?

I have a friend who moved away and is roadtripping her life through America. Our friendship has been harder to maintain due to distance and my extremely busy life.

Currently, I am planning a wedding, in school, and I work full time.

She’s called me out a few times for not speaking to her enough and I try here and there when I can. Recently she sent a video on our girls group chat about how to maintain long distance friendships. I watched the video and downloaded an app that was recommended. I started participating but she had not joined. Today I sent her a message letting her know I played the app.

I got a response that was pretty annoying. “I don’t really have the bandwidth to start this right now”. What do I do? I’m honestly incredibly frustrated.
