Hi Ch07 – Firstly I think you would be better starting your own thread / journal – as this post may get missed here.
You need to get help with things – talk to people on here in groups or one-to-one, it will be difficult to do stuff on your own especially when you are so upset. Also get help locally, through your doctor or local self-help groups like GA or similar.
Also your husband may benefit from looking at and maybe posting on the friends and family forum here. The more he knows about your situation the more understanding he MAY be. Because it is not you who is a bad person here – it is your behaviour that has caused this mess and your behaviour can be changed.
Gamstop is a great starting point and if there are other things you can put in place, please do them. Can your husband handle your finances for you? Without money for gambling it is (virtually) impossible to do so. Also try and fill your time with things away from gambling and whatever triggers gambling for you.
Get some good financial advice about the debts – can the interest on the credit cards be stopped? Do what you can to make things better for yourself. Put as much time into your recovery and looking after you and your family as you used to put into gambling. I wish you well.
