First i must say that i feel with you, i actually have been there, where u are, i hit rock bottom and i actually happy for it since after that i never ever gamble more than i have afford to lose. gambling is one of most dangerous form of addicting out there and have destroyed so many life's in tragedy, and what is scary part is, is that its super easy to get addicted. its really good that you have stood in front and admitted this now.
what i would do in your case now is :
1. if you are deadly broke, since your`r Scandinavian you have one place called "sosial kontoret" where you can get money for your life supply, you go there and tell them everything that have happened and show them your bank account, you then will receive enough to live to your next salary. they will cover your bill and for food. they have also emergency loan where you can loan money and pay them back in small chunks.
2. admit your problem to your fiance and give her ALL control of your bank card and account and tell her how much she and your daughter means to you and you never ever going to let this happen again, we are all humans and we screws things up sometimes. and one more thing, you have now broken your fiances trust, you now need to rebuild it for your self and for her, this only can be rebuild by time and action.
3. You are one of those who do not accept that you have lost, you gamble to you win with no matter what, till there are no money left. this mean you are a competitively person, use this availability to something positive.
4. Change your email like many other have wrote, no matter how many casino you have closed you will receive gambling emails, so make new one.
5. in few weeks, you will get tempted to try some small amounts, don't do it!, instead treat your self with something nice for every time your temptation comes, like a cinema or bake cinnamon rolls with your daughter.
6. Print what you wrote on this thread and put it in your wallet, every time you get tempted, see what you self wrote, you will get disgusted feeling about how gambling made these mess.
7. Enjoy your life, it's what you make of it.
best of wishes
