You desperately are trying to get a solution to your problem by asking others to flock to your donation page and make that 29K magically appear.
Well, sorry, it doesn't work like that.
1. From what i gathered you have a debt of appr. 100K EUR / 8 years-84 months = appr. 1200 EUR + interest = appr. 1400 EUR monthly payment and you are debt free. That is not overly much, it is a lot but nothing to start going around begging for financial help.
Since the bank gave you the 100K you must have some sort of sizeable income + you can take on a weekend job. That should be sufficient to cover your payments. What is left goes to your family, might have to do without some presents/holidays but definitely manageable IF YOU DO NOT GAMBLE AGAIN.
2. You will not overcome your addiction just like that.
You will be a gambler for the rest of your life but if you seek the right help/counseling you will have it under control. It is not any different to drugs/alcohol addicts.
Repeating myself, but do contact a local GA or similar organization to assist you in getting on the right path. They will also go with you to your bank to negotiate the repayment of your debts or at least show you the possibilities, they are experts in that.
3. Stop crying: "I am the poor soul who needs money NOW!". It doesn't grow on trees and nobody will donate 29K to a gambler just because he is shouting loud enough, speak posting the story all over the internet and forums.
4. Talk to your wife, show her every little bit of debt you accumulated, sit down together to work out your total income, your total expenditure/month and what a realistic repayment amount can be. You might even have to sell your car, your expensive watch, jewellery, whatever valuables you have, but if you work together you can make a plan and get through this mess.
Let your wife install GamBlock
on your laptop/PC/tablet/smart phone, whatever you have on devices where you can access casinos.
Cut your bank cards today! In front of your wife.
Self-Exclude from every casino you registered with! In front of your wife.
If your wife is not prepared to do it, which would be understandable, then talk to your brother/sister/good friend/parents/grandparents/uncle and see if they are willing to assist you in your recovery.
