Hi there! Sorry you had a bad experience with a chiropractor. And as you don't sound like you want to go back to him, I wouldn't. There are no-force chiropractors, which in my experience are more effective in adjusting; definitely more gentle, which makes a difference for a more delicate body type. And big plus, it comes with absolutely no "bone cracking"!
There is also something called "muscle energy technique", which involves movement to re-adjust and re-align the body. You could do some reading on the internet (there are youtube videos) and see if that's something that resonates with you. Maybe there is a practitioner in your area.
Hope you feel better!
