Also, do you have personal health insurance? You can submit the claim to it for the hospital bill. There are all kinds of "Primary" and Secondary options. You may even be able to ask your homeowner's insurance if you carry it to cover a portion of it.
Let me know how this works out.
Just so you know, I also do a "Karmic Repair" almost every day. You will be well because of the choices you've made, I believe that 100 percent.
You just may have received it already by not being seriously injured from the impact. Losing consciousness is a big deal! If you are well, you're already being repaid. Continue on the right path, and people like Alan from the other site and those here wanting to assist you will present themselves.
Anything I can do, just let me know. If you simply need someone to talk to, or turn a wrench for you, I'll drive up.
This can happen to any of us, anytime.
You are well, and that's all that matters. I am available anytime if you need assistance.
Keep your head about you, and don't lose site of what's truly important. Money comes and goes, bikes get repaired, but you still being around and functional is all that is important. I know it's a cliche, but think about it.
How would you have handled it if you weren't the one in the bed but the one looking at someone you cared for in the hospital? That's how they felt about you. You have succeeded already by being well, which is all that matters to the people who care for you and rely upon your direction, like your son.
Be well.
