please don't think of it in those terms. The poetry forum is there to help. We want people to get constructive feedback so they know where they can improve or if they are on the right track, what works and what doesn't. I don't think anyone there believes you are not good enough. We believe anyone who tries and puts there stuff out there has courage, and is seeking truthful feedback.
Keep working at it. Take the advice given. If you think people aren't getting it, find out why and work on it, or explain it to them so they do understand it and maybe a glimpse at your motive, direction, inspiration, etc, will give them what they need to get you and know how to read your work.
