You're in a slight bind on this one. These movies exist and can be interesting and life-changing if it gets to the right audience at the right point in their lives.
The problem is you have to sell this idea to an audience that is 95% not going to be the right audience at the right point in their lives. To the rest of us cranky old people the "harsh realties" of middle school sound like a dream. A million years ago when we were in middle school, they were far from a dream, but looking back on them its hard not to be a little dismissive when we've had years, decades even, to better define what really matters to us.
If I'm remembering correctly, your last thread for this, struggled with here. There were attempts to try to refocus the elements of your story to add more mass appeal, or to better define or increase the stakes. I'm just not sure it can be done here without sacrificing elements of the story that are likely important to you.
This is something that has to stand on the strength of your writing and story telling alone. Most people will be dismissive, but a few will want to look deeper and you will need to hook these people with the depth of your story and weight of your emotions. I suppose what I am saying is that logline feedback probably isn't going to be particularly helpful for you at this point in the game. Focus on your story and staying true to yourself.
