It sounds like you are having a time of it. I'm so sorry.
I do think you should go to the ER. You don't know what they can do for you until you give it a try. They don't treat everyone like they are drug seekers. You are counting on failing before you even try and that's not good.
Also be careful with the sleeping pills. You don't want to trade one problem for another. Continue to post and tell us how you are feeling. I, for one, care very much and I know I am not alone. There are a lot of caring people who will respond to your needs. Just give us a try.
With regard to your dreaming about
your accident, you may be suffering from post traumatic stress disorder. I am not an expert, but it sounds like your pain is taking over you and your days and nights. You need someone to talk to. Ever thought of a counselor? Well, just a suggestion.
One more suggestion, call your doctor and ask if they have a cancellation list that you could be put on, so you don't have to wait until July.
Hope some or any of this helps you. I do care.

Believe in yourself. Be kind to fellow humans and animals. Take time to smell the flowers and the coffee.
And by all means, when you are down, ask me for help. I will be there.
