Thanks everyone for the comments.
If I go through TAFE, is there still some online support ie: chat forums etc with fellow students? I am leaning towards enrolling in TAFE (which is external paper-based) but I think I would still need some connection with fellow students so hopefully there are forums you can communicate with students on? Don't think I could do it with just a book and that's it! Its so hard working out what the best way to go is, but your comments and advice have really helped, thank you all
