Are Feelings Fiction?

There are endless quotes verifying that we can feel anything into fruition: If we feel it, it shall come is the motto, right?
How much validity do our feelings really have though?
Think about it, think about the last time you confronted someone about how they made you feel.
How did that turn out?
Seriously, how did that turn out for you?
We always recommend to others to share their feelings, but most often, when you tell someone that they hurt your feelings, your feelings end up in an even shittier situation than they were in before the truth.
Why be honest then?
Is there a value in being honest with your feelings and telling others how your emotions educate your decisions?
I do not really think so, but this is based on my own past precedent.
I have realized that all the times I pretended not to give a shit, things went my way. The less I looked like I cared, the more others cared to fit my needs.
What I have realized is that when I let down my walls, when I allow them to dip low enough, for someone to easily sneak in, I end up hurt.
When I pretend to be a tough guy Tuesday, emotionless being, I am better in the world: It is like wearing a shield of insensitivity, where nothing can penetrate your feelings.
I feel that feelings (ha ha) are at the root of Pandora’s box: if you are able to talk about them, you can overcome them, but are seen as weak, however, if you do not talk about them, and learn to live while ignoring them, you are seen as strong and successful, but are unhappy on the inside (but only you see that, so who cares right?).
Which version of life is better?
Where your exterior is shiny and new or where your insides glow through all your actions?
