Wow, thanks this was really helpful =)
I generally do ask for criticism on specific topics - whether my characters are likable or such - this sort of criticism doesn't bother me. Its when I get crit I didn't expect that I have a hard time taking it.
I'm not usually the type to throw a hissy fit though, I'll usually go and whinge about it to myself and then take it out on my writing by thinking that everything I write is sub-standard. It's not a good cycle and this is why I'm trying to get out of it =)

You've been really awesome, I'm really glad you replied to my post =)
