Why is my default reaction to want to run away?

[RunNolaRun]

I've had a pretty average day. One letter of an outstanding balance which I can't pay. One mildly critical comment from a stranger, comment from DC's teacher about something. I just take it all so personally. My thought it always I could just get all of our stuff, put the kids in the car and we could just drive.
I have family. I know I'm good at some things (my job) but I seem to have no coping strategies, my mind just goes straight to run away, don't talk to anyone again, never go back.
I've never actually done this. Once I booked a flight but never actually went through with it. I know it's such an unhelpful way to be. I just can't help thinking that if I could just get away from everything then I could survive. Honestly even slight criticism makes me feel like just never going back to work/ school/ home. I think I've always been like it. I ran away five times as a kid.
Just want to change but I don't know how. Does everyone have these thoughts?

Avoidence attachment maybe

@Pantsonfire74 where would that stem from? I had a good childhood, no trauma

Avoidant even

I used to take everything personally until I got a bollocking for it from my caseworker at the jobcenter. She said STOP TAKING EVERYTHING SO PERSONALLY MOST OF THE TIME IT ISNT ABOUT YOU. And honestly, she changed my life. Since she said that to me I've been able to detatch (mostly).

I will also say that having a great boss helps. Any criticism or feedback is of something I've done rather than me as a person. And I live in a country where strangers never talk to each other so I dont get any comments.

I'm still not great at conflict though. I commented on LinkedIn about the Heard Depp outcome and someone has replied in capital letters telling me to stop, and I actually started shaking. I fully intend to reply though, because strangers on the internet dont get to tell me what I can or cannot do, what I should believe. And I am well aware that I need to get a grip, or maybe just a thicker skin.

If it is your natural reaction, perhaps find a way to use it to your advantage. You can't actually run away but could you have somewhere you escape too? A special spot that you can leave for that might still give you that fleeing sensation? Somewhere away from the rest of your life that you only use when you feel the need to run?

I am the same and have a very strong flight instinct. My husband is the opposite and always wants to stand and fight his corner.
I think most people fall into one category or the other. So fight or flight instinct kicks in depending on which kind of instinct is uppermost.
