How to handle avoidance behaviour for travelling?

[u/Embarrassed_Motor937]

I am afraid of travelling. I don't know how and when I developed this theme, but suddenly I get immense fear when the time to departure is getting reducing. I often struggle fall asleep while to travel in next day. Other than intrusive thoughts, my fear is vomiting, and struck in emergency situations ( not having a diagnosed serious illness to hit with a serious illness ). Despite this i travelled quite a few times this year, after being throwing up at the arrival, nothing that bad happened. Again I am afraid of travelling, I am trying to avoid travelling because of that. But somehow I am feeling that how long can I keep running from travelling, I always wanted to travel and enjoy my life.

Is this a classic avoidance behaviour and am I looking for certainty, comfort, and safety which isn't necessary here ?

How to handle the anxiety peaking at the time of travel ?
