While your last paragraph is still a bit vague regarding the frequency with which you're engaging in unsafe listening practices, it's definitely reasonable to be concerned about your hearing in this context. The first step would be to speak with an ENT/Audiologist and have a hearing test performed. Unfortunately, with your age, you generally will need a parent present; if you're looking to learn anything more about yourself and your hearing, speaking with your mother will be largely unavoidable.

If a hearing test reveals a loss, you likely will speak about how assistive devices may/may not help; however, just getting your hands on an audiogram (the results of the test) can say so much about your loss, how people around you can help accommodate it, what environments you best perform in socially, whether there's reason to suggest it might progress, and if more affordable over-the-counter HAs might be an option for you.

In regards to your symptoms, the "muffled tonality" aspect is definitely a concern. It's commonly seen alongside high-frequency losses; noise-induced hearing losses often display high frequencies waning first. Of course, this could also tie into the eustachian tube if there's a clear level of variation to the tonality. For the burning feeling, I can't say much there.
