Yikes! Good to know that's how it comes across (a little too late!) . I'm a pretty friendly person "IRL" - sometimes it's tough to get your writing voice to sound close to your mental/speaking voice...
Look, first impressions can change, so probably no harm done. I think possibly this is a case of "trying too hard" out of sincerely good intentions. Just take it easy, try to earn people's attention and advice by finding ways to give to them first.
Those mental notes are helpful.
