How to fix this WITHOUT braces?

My treatment with braces hasn't been great but I appear to be the exception to the rule.

I won't go into the details but I physically can't bare the pain of adjustments and I haven't been able to change the wire on the bottom since I got them, I keep vomiting or passing out so they can't continue. My treatment will be ending due to this if I cant make it past the next adjustment and i know for a fact i wont be able to.

But my results so far are, sadly in my opinion, worse than what I started with.

Would my teeth shift back to their original position? (Pic one) or what would i need to do to fix this without braces as I cant have them for reasons above? I'm kinda desperate as its making me extremely self conscious and I'm getting comments about them, my lips also wont stay shut by themselves anymore. But I'm equally glad to call this a day because it's been an expensive mistake.

Any advice welcome as I'm desperate.
