Angela, I think you're list is a great list to start with. Just like anything, start slow and build on it. Think about what REALLY makes you happy to do, what concrete things you could to do show HOW you are more independent. (Like change a tire?, lol)

As far as being insecure, start to do these things on your list and then challenge yourself to do something you've never done before.

Building up the things you like to do will build your confidence.

I've started to do things now that I often wished I could do or didn't have the confidence to do and it has made me a much more confident person in a short time. It works!
