It's perfectly normal to feel that way, Maddie. I've done it - heck, I still sometimes do, although it's getting weaker.
We've all been in "an abusive relationship" - some choose to stay; we are the ones who decided to leave. But you can't expect to come out of it with absolutely no problems. We may feel we're doing fine, but then suddenly only the "voice on the phone" of the former "spouse" may be enough to trigger the fear again, even if the "spouse" is thousands of miles away and can't hurt us anymore. It's a natural, protective reaction.
But it gets better.
What's weird is, after I had 'left', I even started to fear the predictions of other idiots out there - well, not really fear I guess, but it would give me an uneasy feeling, and I would feel a sense of relief when their dates came about and nothing happened. And here I'm talking about people claiming specific dates for UFO invasions etc..... It's stupid. After a while though, you learn that it's all bull#%¤#, and nothing to be scared of.
We're like an animal that's been hurt by a fire once, and now every time it sees or even hears the sound of a fire, it will get scared. But after a while, when fire from fireplaces etc. actually don't hurt the animal, it will slowly adjust and learn that it's not dangerous after all.
OK - enough with my stupid analogies...
At one point I thought "I'll be happy on January 1st. 2013 - then I can breathe a sigh of relief." But the problem with that is that these a¤%holes will always be there, making their stupid predictions, and unfortunately they'll be with us the rest of our lives.
Best just not pay any attention to them at all, and just live our lives.
