OP
There is a specialized forum which it might help to read to bring you up to speed on the jargon, legal procedures and issues you need to know about, as well as an idea of the various realities you could be facing. If nothing else it will give you a place to talk and be heard by people who do understand how you feel.

I've only skimmed it but the seems to be lots of people in your position on the thread entitled "where is the light at the end of the tunnel?", might be worth asking advice from the posters talking there.
Reading other threads would shine a light on the advice, information and perspective of people like your husband, so you are not playing catch up all the time and trying to second guess what he is thinking or what he has found out.
I would also recommend finding out where your nearest RL expat groups are.
Expat groups can descend into nasty bubbles of self perpetuating misery sometimes, so be sure to take the temp of the group before you get in too deep. Hopefully building up a network or people who just "get you" on a cultural level and speak your language will take the edge off the desire to be back home. They could be an invaluable support and by being networked you could find opportunities that while not as good as being home, make the UK more bearable.
And maybe popping into your GP to get the wheels in motion to get you some counseling love, this is a very high stress situation, sometimes it is better to be proactive about getting help before it becomes a time sensitive issue and you are left dangling in a queue just when you need help the most.
