I am battling anxiety for more than a year, mine was triggered by a road-trip with my wife - and long story short, I end up in ER thinking that I had a heart attack. So since I managed to almost overcome my fear of dying or having some medical condition, but still these intrusive thoughts  re appear if I just intend to think about having a trip longer then 100 km.

SO - is there any tips and tricks that helps you if you when travelling? 

* Have to mention that I am the only driver;
* My anxiety abruptly just come forward from time to time when some external factor affects me ( like my wife talking about some news, or I see a dead animal on the road or random stuff like this ) - Idk if this is important but I felt like I need to share this information. 
* Oh, and I am freaking out If I have to leave my town if Its 30+ C; I hate heat.
