It's a pleasure to meet you tjbird,
I'm Pete/ASB

I've had RSD/TOS since 83, and then another accident gave me a head injury in 98.
My story is posted elsewhere.

You certainly present yourself well, and, I cannot lie, you do have a "tough row to hoe".
That's what Dr S. told me on my initial diagnoses.
Yes, rsd can make your bones feel like they're on fire, and your skin cold. ice cold.
Or, the opposite. Rsd has it's own mind. That, you'll need to get used to.

I feel terribly for you, about your husband. I have had two wives like that, the first, decided she didn't want to be married to someone on "drugs". (She left me with my two young children, and proceeded to "party the town".) Second wife, knew of the rsd, but then, the second acccident. She is still in the process of devouring my and my two children's lives. (She's got me, taking from my disability income, threw us out of MY house, and is now trying to take that.) She stole all my bank acc'ts with forgery, and I'm catch 22, can't afford a lawyer. THANK GOD, I finally found one who will work with me! In Philly we have a legal clinic for the disabled, and they found me one who I will meet tomorrow. I'm praying.

It still annoys me about your husband, whatever happened to "In sickness and in health?" Both my father in laws asked me that, about their own daughters.
(You know what, even though my children don't speak to me at the moment, I know that they're going to have strong relationships, they do already, they've learned so much from what I've been able to teach them, and what they've witnessed). They'll be back as soon as "she" is gone.

As for your husband, he may be Afraid, intimidated, or some such emotion, but give him a chance. Invite him to the doctor with you. All of them. If he doesn't come around, I hate to say, the writing may be on the wall.
I don't know what causes people to be like this. I couldn't do it that way.

But, for your main question, "What comes after "Life as I knew it is Over!"
I'll tell you what happened to me.
First off, only a small part of your old life is over. No need for a ceremony.

You should embrace your new life. The more, and sooner you do, the better your "new life" will be.
Fight it, and it will fight back!
Accept it, and have trust and faith in your higher power. For me, it's God and Christ.
"His will be done". gets me through every day.
I ask, I pray, what is it, God, that I'm supposed to be learning today? Help me!
He does.
There are setbacks, often. Roll with them, find a "comfort zone" for yourself!
A place where you can take the pain, and get comfortable enough to pass the time, until the worst passes.

Remember too, there are three points to dealing with RSD.

Your meds. (your doctors).

Yours emotions. (Your psych doctor, and faith).

Your body (Exercise, and beat the cycle of pain and depression).
Take care of yourself, your mind, and your disease.
Keep your faith.

Keep your friends, and you'll find that you will lose some, and gain some.
(But, You cannot lose what you never had)!

You have lots of new friends here, Don't EVER hesitate to contact Me, ( A PM is fine ), or any of us.
I'm new here myself, and have made some good friends already.

You will do well, because you have reached out, and are not balled up doing nothing.
So, you are an action person, and this will NOT beat you!

All the best to you, and, I apologize for sometimes being too straight with my speak. It's my head injury, that sometimes does that.

I truly empathize with your situation.

Peace and love

Pete
