Please help.
I’m 16 years old. Over time I’ve noticed negative changes to my facial structure and side profile, especially related to my nose, lips, and how tired my eyes look. Mentally, I feel chronic fatigue and loss of concentration. This is due to a multitude of bad habits that I am only properly aware of now: I started to chronically mouth breathe and sleep with my mouth open at a young age, constantly chewed on my nails, and slouched in front of devices. I needed orthodontics and got braces with rubber bands and a palate expander when I was 13 - now I wear retainers every night, but I think that the damage has been done. All these are pictures of what I look like currently and the last picture is when I was a child, can’t remember how old I was in that picture but I marked it ‘before‘ in red. I hate my teeth and my disgusting gummy smile and I feel like my facial structure has been completely ruined. I was told that I have a narrow face and my orthodontist said I have an overbite, but the root cause of mouth breathing and poor posture was never properly corrected early on. I was told to “close my lips together” but that was the extent of it. I’m currently having trouble with anxiety and struggling to breathe normally and having frequent insomnia previously had sleep bruxism. I’m so stressed about this and my physical and mental health has been severely impaired and feel that my life has been ruined. I stopped my mouth breathing now, but it’s noticeably harder for me to close my lips together. Realistically, I’m aware that mewing can’t entirely fix or reverse structural problems, but I’m going to try and improve my tongue posture from now on. I just used to be so beautiful and healthy before... My parents are aware about some of this, but I have health anxiety too which can confuse them as it’s difficult to understand which symptoms are real or not. I don’t think they completely understand. I’m currently not in the position to have surgery or anything like that and the orthodontics were expensive. I need some advice or reassurance of some sort, please. What can mewing actually fix? Are these problems all too late to correct?
