Actually not really, it's funny because I am the total opposite online than what I really am in person.
I talk a lot and make sense, I am still quite shy, but I open up a bit more in a face to face setting, it's more comfortable for me.
When I am online, I seem to withdraw quite a bit, I feel I can only rely on words to convey my thoughts which may or may not come across as intented, and I don't have the body language of the other person so that I know how my words are being received the way I want them to.
And sorry to the poster, I don't have any advice, I am in a similar boat to yours.
