probably a slight form of panic attack, after all.. being empathic means you are more vulnerable to being hurt than the more hardy types. So maybe it's not a bad thing unless it prevents you ever forming any relationships.

Is it only regarding unwanted romantic attention?
Can you share more about the specifics of the situations?

I've felt that way.

Perhaps you had thoughts like:
"How did I let this happen? I feel responsible for this person." (responsibility)
"I never wanted to hurt anyone. I don't want them to feel this kind of pain." (pessimistic empathy)
"Could I be wrong about how I feel for them?...No, I still don't feel it. Damn!" (second-guessing)
"I must save their feelings, fix this, stop it from getting worse--I created this." (the illusion of control)

Combine empathy with analysis and creative intuition and what do you have? An excellent story-teller. We take the facts that life gives us, and then create our own story of it--a story that is sure to cause our feelings to over-react. What could be a healthier approach then?

New thoughts:
"It's not just my fault entirely if others like me. Attraction is natural and I am flattered." (balancing the load)
"Of course I feel uncomfortable by unwanted interest, anyone would. These feelings are normal." (permission to feel)
"I have to give the person enough credit to be strong enough to handle rejection & disappointment, even if it's hard at first." (optimistic empathy)
"I can be direct with the person. I definitely know how to give the gentle honesty I would want to be treated with." (self-empowerment)

Within an INFJ is a double-edged sword. We can use our creative, analytical, sensitive mojo to create stories that terrify us, or ones that help us cope with life's curves in a 'more effective and less affected' way.

After all, the positive stories are usually the more true ones anyway!

Just my 0.02...
