I've been on a lot less lately too (too much hauling water and trying to keep everyone alive in the drought = pooped lockwood) and find it hard to catch up on the threads too.
As for the rant, Skye... no one can make you feel inferior unless you let them. You have much to be confident and proud of and no, that does not make you conceited, just real.
Based on the description, this other person sounds plain and simple jealous so don't let her problem and insecurity become your problem or insecurity.
While most here do not know each other in person, you are well loved here by many...... and it is because of who you are on the inside since we can't all see one another.
This other person's opinion (or actions) matter not.
Of course there is a small chance you could be some kind of an ogre in real life who is a great actress on here, but I doubt it.

Sorry to hear about the feet. Sounds like foot soaks and a massage (by a hot Maori) are in order.
