My deepest sympathies for what you are going through. I was also someone with absolutely no support behind me. I was able to vent on these boards and also to my GP. It may be worth looking into some counseling, meditation therapy, hypnosis , pain management etc.

Nobody should have to go through this alone.

As far as work is concerned, it's hard to concentrate on work when your in so much pain, but we all have to put bread on the table one way or another. You may consider asking your husband to get some paid work and if you can scaling back your hours?? I dont know if that's even possible.

If all else fails just vent and vent on the forum. Trust me I totally get you.
Yes it sucks big time!!
