Best for your case is AM6 or if you want something cheaper LTU (90$) or EPRHA (free). Had similar problem as you. I have used to be shy, had hard time talking to people, felt insecure and needy. While I havent used AM6 (OGSF included in it) I did AM5 (older version, about 10 times less powerful + without OGSF) and gotta say it was really hard run (lots of depression, basically fighting old believes), but it changed me from the core, all insecurities are now gone, at the moment I am feeling really strong and not caring what others think about me. Of course I have a lot improvement to do, but in whose 6 months I have had more personal grow than in the last 10 years! By the way you can read some other peoples journals if you want to find out more!
Good luck!
