I know the feeling, more often than not I choose not to burden others with what happened to me, I am embarrassed by it, and I fear people will look at me differently if they know.
Don't think for a second though that your experiences aren't as severe, that's the wrong way to see it. I don't think the purpose is to compare and see who's had it worse, so hold my hand and I'll hold yours, because I'm new too, and I'm reluctant even though I have anonymity here.
