In this post i'll state my problems and concerns.

Posture:

I recently just discovered my posture wasn't in the best condition, so i decided to watch this video: https://www.youtube.com/watch?v=TQqgf8kB6R8&t=0s&index=26&list=PLWrirXEOSTIGVwyt-bppa4lPS168Jw3_L. These past days my posture has gotten a lot better, but i noticed something odd about my neck. I'm following the instructions in the video perfectly, yet when i have good posture, my neck looks like it's moved a bit forwards. It doesn't change no matter how much i tuck my chin in. It could be kyphosis yet i'm not sure. I've tried to implement a more upwards chin tuck, and it seems to untighten my neck and upper back muscles, so i'll keep doing that.

Jaw:

Lately, my mandible has receeded by a great deal, plus my jaw has gotten really tight, where it's difficult to open my mouth. It also clicks sometimes, so i'm thinking i have tmj. When i open and close my mouth it also does a little zik zak.

Tongue posture:

At the moment i just do the cheesy swallow exercise, and wherever my tongue lands i keep it at that posistion. What's bothering me is that i can't seem to get a suction hold, it feels like all the saliva is trapped behind my lips. I can also feel my lower incisors, maybe just because they're crooked, i'm not sure though. My upper dental arch is also asymmetrical compared to my face, so when i swallow my tongue ends up more to the right, than on the incisive papilla. I tried to force it on the incisive papilla for a couple of days, but only negative results occured, so i'm probably not gonna do that again.

Swallowing:

I'm pretty sure i'm swallowing correctly. I swallow by pushing on my upper palate without any movements in my face. The only thing that's bothering me is when i do this, my lower jaw get's pushed a little bit forwards. 

Teeth:

I keep my teeth either slightly apart, or just gently touching. I also move my jaw a little to the right, since i have a slight crossbite.

That should be all, help and tips are greatly appreciated :)
