That is one hell of a hectic post, that hits way closer to home than I would like to admit.
A lot of what you put down resonates with what I feel a lot. Yes I've learned to deal with it a bit better (See my Breathe post), but things like these still leave an impact.
Like the relationship thing I never got out what I put in (well once), I might be pouring myself in to others to quickly when I trust them... but that's just me, it's all or nothing. I am always myself I never feel the need to fake to be someone else... Not everyone can deal with that.

And what I gather from your post is that basically people are talking down to you for being a good person... This says more about them then about you... I would love to say "don't mind them, you be you" but from experience I know that does not help...

Best I can say is... You are a good person and you are not alone
