So, getting rid of pain can be painful. Although it seems counterintuitive, I get it. In fact, it seems closely related to the kind of reaction I had when finally receiving good news.
My feeling is that “hardening” decreases resilience because the hard shell tends to be brittle, fragile, and always under threat. That’s why it’s usually accompanied by anxiety, and perhaps exchanging vulnerability for fragility.
It is absolutely true that a person needs to reduce vulnerability to the extent possible. Once someone hurts you, the best option is to take measures to avoid being hurt by that individual again. Minimizing vulnerability is most effectively accomplished by nurturing strength, resilience, and wisdom. Hardness creates a barrier, partially or completely preventing perception of positive attributes in others, and maybe even in ourselves.
You can set appropriate boundaries, ensure your own safety, say “no” to others without regret, resist manipulation and require that others respect you, all without being “hardened.”
Using logic, critical thinking and common sense is very wise, and as far as I can tell, useful in any situation. Even if you make a heart motivated decision, knowing the facts to the extent possible, is important. There have been times when I was virtually certain that my trust would be betrayed, but I made a conscious choice to be vulnerable to that betrayal. Surprisingly, sometimes those kinds of decisions end up having a net positive effect.
I guess you would call it “conscious vulnerability.” Among other things, it’s a way of determining to what extent another person can be trusted. However, there is no reason to allow yourself to become physically vulnerable. The net positive effect I’m talking about is when after days, weeks, months or years, it dawns on a person that someone cared enough about them to trust them, even while being aware that it was likely to lead to disappointment. At times, it’s enough to convince a person to rethink their philosophy on life and become far less likely to betray someone else in the future.
The inner child is there, for better or worse. This child wreaks the greatest amount of havoc when someone tries to deny it, or convince themselves that they have it completely subdued. It’s best to acknowledge what the child is trying to communicate, usually through impulsive triggers, and weigh those impulses against logic, critical thinking, etc.
Acknowledging the inner child is evidence of maturity.
So, you wish to be appreciated and feel close to others, but without physical affection. I hope you find a way to accomplish that. You very much deserve to be loved.
