Chickref, I hope that things seem better after a night's sleep. If it is still eating you, I'd urge you to take up Simon Thomas's offer - I'd second Phil E's view that you are unlikely to find a more capable advocate on your behalf. Ask him to call you though - his company can afford it.
Taking wild stabs in the dark, I'd guess that you've become aware of facts that seem to suggest: a) people in authority consider your gender to count against you in a fair competition with blokes; b) people in authority consider your relative youth to count against you in a fair competition against other referees (usually blokes); and c) people in authority seem to consider that some complete to$$er is sufficiently more capable than you as a ref to warrant upgrading him while leaving you choking on his dust.
If this is at all accurate, then I'd offer this thought: selection for promotion is an imprecise art in any field, and there are usually more capable candidates to choose from than places to be filled. It's possible that the perception you've gained does the selectors an injustice. However, they can't (and won't actually want to) keep a good ref down for long. In this game, waiting for "dead men's shoes" takes less time than in many, as the physical demands on a ref mean that time takes an obvious toll in middle age. The effort of waiting probably weighs more heavily on a young and eager ref than on an ageing ex-player; but the log-jam will free itself in the not-too distant future. In the meantime, you can be honing your skills to make it harder and harder for them to ignore you when that happens. If you examine yourself critically, that honing process almost certainly needs to happen - few of us are as good as we'd like to be.
I'd also mention that this sort of thing is sadly a challenge you'll encounter in most aspects of your life. I hope you'll face the challenge and overcome it, rather than walking away from it. In your shoes I'd also change my view of why I ref; so stop reffing to represent your Association, and take the field to facilitate the players. Membership of the Association merely gives you a glow of reflected capability so that they have confidence in you at the kick-off; thereafter, give them confidence in you because of what you do, not because of which jersey you wear. That way, you can thrive despite the shitty Association, not because of it.
