6 days is great - it's amazing the clarity you will start to get as you go further and further into the gamble free journey. You might find yourself beating yourself up a fair bit, as you start to see reason again it will be hard to understand how you did what you did. Don't get stuck there - try and forgive yourself and remember that it's not because you were stupid or some kind or reject. You were fooled by a lie - we all were. The gambling industry has invested billions $$ over the years to figure out exactly how to take advantage of people like us. You think they make all their profits off the average punter who blows a few hundred $$ a week? Of course not - it's off addicts like us.
Can I make a suggestion - start to put together a bit of a plan of what the future looks like for you. An ideal future say in 3-5 years time. Work backwards from that and figure out what you need to do to get there. On the financial side, if there is significant debt, perhaps find a professional to talk to in order to figure out how to make it less of a burden. If your dad has the financial resources to help you, it's probably best you come clean now rather than wait in case you relapse.
The most critical thing is that you are engaging with people and organisations to help you beat the addiction. It is extremely difficult to do on your own. A small relapse can seen innocent at the time, however it can easily drag you back into that old lifestyle.
In terms of all the lost time - you can make it up. By using this episode to become an extraordinary person you can actually change the past. Think about it - you can use it as motivation to do things that you never would have otherwise done. You can actually create a new and exciting future out of all of this that would otherwise have not had been possible living an ordinary and safe life.
