TD, don't feel guilty. If you're happy here then stay. No one would be any less than thrilled for you that you are making good progress. I find reading your thread really helps me as it gives me a bit of hope that I should carry on. You first reason is great, I love it and you are absolutely making a huge difference to me! I don't think I would have got this far!
Today sounds intriguing... I am keeping my fingers and toes crossed for you. It sounds like you are taking a risk??! Well, hey it's worth a try and you might really gain from it. Let me know how it goes!! I doubt, whatever it is, that you would go back to square 1 :-)
