Hi and Welcome!
I am really too new to offer a whole lot of advice. There are people here who are very knowledgeable and, thankfully, they are very generous with their knowledge. I will leave the technical advice to them.
I just wanted to empathize with your fear that this plan just somehow, someway won't work for you. I am with you. I lost great the first week, this week was a small loss (and there are reasons for that for me), but due to all my past failures and disappointments, I live in fear that this plan, too, will mysteriously stop working. All I can offer is a hand of friendship and support as we all take this leap of faith together. Stick with it and look toward next week.
