Mark, as you've said, Crossfit isn't for everyone. (I've been a dedicated Crossfitter for over 2 years.) You stuck it out for long enough to have given it a really good try, so don't let anyone make you feel "inadequate" or "inferior". At my box, if someone gives it a reasonable amount of time to see if it's for them, but then moves on, there are no judgements made or hard feelings.
Take what you've learned, get advice from others who are knowledgeable, and make your own fitness plan. The important thing is to keep moving and have fun!
You make your choices, and you live with them. In the end, you are those choices.
