I waned to add some things. I'm definitely not overweight at 5'4" and 103 lbs. Also when i wake up in the morning I feel stiff and I feel like i got hit by a truck. It takes several minutes for me to become oriented, i'm almost always confused when i first wake up, and i almost always feel weak and overwhelmingly tired. However, once i am awake, i feel okay I do not feel fully awake until the afternoon, and by 1-2 PM onwards I tend to feel pretty normal.
I've never been a morning person, but for the last few years mornings are straight up painful.
Any idea what this could be or where i should go from here? Thank you for your time!
It definitely sounds like you have a sleep-breathing problem, mainly due to your small jaw. Inflammation and swelling of your tongue due to reflux that's brought up from your stomach can cause your tongue to swell and leave marks on the side of your tongue (teeth marks). You don't have to be overweight or even snore to have sleep apnea. I strongly recommend a sleep study or some way of screening for and treating a possible underlying sleep apnea problem.
