I know it can be really hard. About a year and a half ago, I was in a car accident too and it's left me quite physically annoyed let's say so, my neck and back really bother me and because I am not in the USA (where it happened) it's kind of a nightmare with treatment etc... all has to come out of pocket so trust me, I understand and in no way was I trying to be insensitive.
I will recommend something that may be out of the orthodox but it helped me tremendously and served to change my life. My accident was in Texas and I visited Austin to see a friend. For some reason, I felt weirdly called to try something called reiki... I had never done it before and barely knew anything about it but I made an appointment with a woman there.
That day, more pain dissipated from my body than I could ever make sense of. After that, along my travels I vowed to study and learn that modality and since, I have become certified in it. It's helped me not only physically but emotionally and mentally get through the blocks of the pain.
It really helped me and I strongly suggest looking into it as an option to clear out that pain for you so you can move on from it and leave what doesn't serve you behind <3
