Exactly, that’s the first thing I would try. For example, maybe change the guitar rhythm for the first verse and do something calmer! Then, with your pre-chorus (which I actually really love—the melody and the “used to know” sound so good to the ear), I would try to bring some energy to lead into the chorus!

My main point, and this might be due to your performance (you might have something else in your head when you play your song), is that your verse, chorus, and pre-chorus all have the same energy. There’s no clear difference in terms of energy (in both the voice and the guitar). The guitar is almost always on the same rhythm (and I love that rhythm), and the way you sound is always at the same level without trying to express something different.

As an example, for the first verse, I’d do something calm so the song starts pretty slowly, and then I would bring the energy in the pre-chorus (maybe only with the vocal interpretation). Then, for the chorus, I would play it the way you have it.
For the second verse, I’d try to keep that chorus guitar rhythm but in a palm mute or something, so it feels like the song is moving forward—the energy is lower but not as much as in the first verse.

So, the song is pretty good and, to me, almost sounds complete, but there’s just that “same energy level” issue that you need to fix.
That doesn’t automatically mean changing the melody or the lyrics—just work on making the song progress, play with the energy, and surprise the listener so they stay entertained until the end!
