Do you still find it hard to share feelings with others?

Not with those I trust and feel close to.  But I had to learn the hard way about trusting too easily.

Not in the least, I am happy to tell anyone anything about how i am feeling 

There are a rare few with whom I share my feelings . My wife is not one of them, nor anyone else in my family.

Yes and no.  I find there are but a select few I will truly share with, and there is really only one I can share all with, but due to circumstances I cannot even talk to him now.  When I am angry, however, it shows, even if I do not discuss it. 

When I find you worthy, I'll share my feelings with you.

Nope.  But sometimes it is just unnecessary.   I think there is a time and a place to do so and not to just dump on other people to have a sounding board whether they may like it or not.  

But when someone is feeling raw about something in their lives, oftentimes it helps to let them know you have been through something similar and it is okay to feel however they feel.  It helps to know someone else understands.

Yeah, I have the emotionless robot facade to keep up with.

The hard part is that people I talk to tend to address me as "Moron". I figure the decent people must be the ones that avoid me.

If the feeling you are talking about is the feeling of the need to kill, then sharing the thought is not an option. The target is too likely to make himself scarce, or share his feelings, of fear, of victimization, with others. Too counter-productive I think. Give yourself the best chance, that's my motto.
