Can you post pictures of some of your shows?
I say this because for having competed for so many years, you seem a bit disoriented about your goals and how to achieve them. Did you ever put yourself in true contest condition?
Gaining that many pounds of muscle is possible when you're young and starting out, but you've already come a long way.
You come here looking for moral support, I support your desire to compete, just be realistic about what you can achieve. For goodness sake, you're not that old and you can push it some more.
