Hi apog, and welcome to the forums. I have recently gone through the same experience, and got my IVA approved on Friday.
You have made the biggest step of all by admitting your debt problems, and working out a way to try and resolve them. I have had letters from 12 months ago when I first started missing repayments, so I know how that feels. I managed to shut out the letters for a long time, but once they reached a certain "threat level", I couldn't sleep, so I knew I had to do something. That's when I started researching my options, and approached my IP who was superb.
I too have not told anyone of my situation, not even my partner or parents. I know my parents especially would be disappointed with me if they found out. It was a tough decision for me to make, but I have decided against telling them; but I know that doesn't work for everyone.
The five year period is definitely a step forward into a new debt-free life. Yes, the 5 years will not be easy, you will have times when you feel down, but then I bet you will have more down times if you continue to let the creditors pressurise you into charging orders, CCJ's, bankruptcy petitions, etc.
I think of the positives of an IVA - I am buying everything from money I have earned, I get no further letters from creditors, etc.
I had a list of about 20 questions when I first spoke to my IP, I must have asked another 40 since then as well. As aguise correctly says, understand every one, and seek clarification if you need to. You can even come and ask us for our opinions as well.
Finally, may I wish you the best of luck with your meeting, and you have taken the first, and probably most difficult onto the bridge towards a debt-free future.
