Short back story, I moved my family and I back to our hometown last year due to many reasons, one of which is because my previous job was so stressful I battled anxiety and panic attacks on a near daily basis. I also didn't like the location we were in, people were terrible and weather was awful.

Im now in a place and job that is so much better. I have little to no stress in my current job (And I get paid more than I did at my stressful one). Weather is great and im surrounded by family and love.  Life overall is great and is night &amp; day compared to how it was previously. 

But I still get these random bouts of anxiety even when I can't think of anything wrong or stressful. It doesn't last long (Maybe 20 mins of heart racing faster than normal) and isn't debilitating like it was before, but I can't figure out what is causing it or why it's happening. 

Any insights or tips? Thanks in advance!
