Don't know what's up

I finally got past the anxiety and felt good on Saturday.  Sunday and Monday I was ok but tired.  Today I am not sure what the deal is.  I am not exactly having full anxiety.  It is more like waves of discomfort.  I have no idea why I am having such a bad stretch.  Sure a few things have changed this last couple of weeks.  Class is getting harder and my  boss left so I am the only IT person until May 1st. On my internal stress meter though it does not seem nearly as stressful to me as when my boss retired last year.  I have a lot less people on my ass these days and even though I have been pretty busy things have been going ok.  I am almost done with my comp science final project..another raspberry pi project.  This time I am using it to create a timer for drip irrigation on my patio.  Steve helped me build the drip system on Sunday afternoon.  Now all I have left to do is change the timer for the pi and see if the wireless remote that I hacked will reach through the wall to the patio.
Sunday I had wayyyyy too much coffee and  my heart was pounding crazy fast.  I know I need to find a way to give up the coffee and smoking.  If only it were that easy.
 
Still not sure why I am having these waves today.  Everything is fine, I am def. not sick.  If anything it seems like an easy day.  I guess this is what frustrates me about this disease.  Just can't find a reason for the issue. Grrrr
