Whiplash pain at all time high 6 months after crash

6 months ago I (23F) was rear ended sitting at a red light as the passenger. I was reclined back, laying down when my friend stopped extremely short to avoid crashing into the person in front of us. My body flew up in a weird way, we didn’t crash and took a sigh of relief. Then all of the sudden a car slams into the back of us and I flew forward again. I didn’t have any pain until slight neck pain a few hours later but I went to work that night. I went to the hospital after work, got looked at and they said I was fine. I started getting gradually worse and was having bad pain in my upper back, shoulders, and neck. I started seeing a chiropractor who I saw once/twice a week for 4 months. I know this is a long shot but I truly think this chiropractor made my injury worse. My pain has increasingly got so bad, every day, every second to where it’s impacting my quality of life. I stopped going as much and this much I finally stopped going and went to my first acupuncture appointment. She did cupping as well as acupuncture, and when I got up at the end of the appointment I was in the most pain I’ve ever been in, and my whole back was dark purple. I could’nt even turn my neck. She rubbed it out for me and told me this was normal to an extent and that I should feel better in a few days and go back to normal after about 6 sessions. I also forgot to add that on top of all this, I always have the urge to crack my neck/back and do it atleast once every 5 minutes and I constantly get massive cracks. If I shrug my shoulders they make a huge cracking sound, and if I rub my neck or back you can physically hear a few little pops. I’ve never had issues like this before the accident. Has anyone gone through something similar to this? I can’t take it anymore!
