Hello, I decided to treat my recession for improvement of my looks and breathing issues. But as the threats of the epidemic remians and I dont have that kind of money to pay for a doctor I decided to make everything myself. But I doubt I understand everything about the bone structure and application of the techniques correctly because I am a non-native speaker of English. For this I ask for you benevolent gentles guidence. Heres my story:

28 year-old female. Had orthodontic treatment at 20(palate expander, braces, 2 upper teeth extraction, 2 upper wisdom teeth extraction). Have spine issues, left shoulder rounded, very tight shoulder and nect muscules on the left.

My nose is deviated to the right. Left jaw is visibly lower and more sticking out in comparison to right side and this makes my left cheek look hollow while right cheek looks more plump. Left side of my chin is lower.

My palate is very deep, narrow and small. My whole face is visibly recessed and shrunk. 

I tried mewing and it ended up as a disaster shrinking the left jaw more so mewing is not an option. Facepulling doesnt seem to work. I try thumbpulling but I dont know how long I can do it and how slow it shows its results. 

I think expanders are the thing for me. As I used one before and having making tutorials online I can make one myself and use it. 

What do you think about my case? 

What kind of expanders should I use? (I see there are different types and ones with linkage to different set of teeth)

What other devices or techniques should I use?

Would like to hear your opinons for creating a guideline in my treatment. Thanks to everyone who helps!
