Hi Alex,
Nothing really unusual about that at all. With respects to any revelation on any subject that you aren't confident with, people will always challange you. The more confident you aspire in any conversation, the less challanges you'll have. I'm certain you are right about yourself. They are just not comfortable with you, at the moment. Again, their problem, not yours.
Much about coming out is to whom and when. And it should always be prefaced with your level of confidence. If you're not feeling right about it; Don't.
Just try pinning your explanatation down to 3 different approaches. Practice these, then go out into the world, and when the time is right. Let them know. Embrace this time of transition for you. It's unique, it's you, and it's marvelous. Try not to let others peoples opinions/feelings stifle yours. If people aren't happy with your transition. That's their problem; not yours. I often find when people disagree with me (they don't get any further work - ROFL) the statement, " I appreciate you thoughts on the matter, it's a pity you haven't been able to appreciate my perspective on the matter. Anyway, I'm quite comfortable with the way I feel," works quite well.
Chin up man. Back on the bike.
Be safe, well and happy
Lotsa huggs
Catherine
