One thing you may want to consider doing is to look for the message and ignore the tone.
Intention and relevance are what matters. Answers, that is what you are looking for. Everyone experiences frustration - but the fact is: if the message has some valid information, then that is what we are looking for.
May not be what you settle for in the end, but is there for your consideration. That's what CureZone is all about: shared opinions.
You've worked so hard just to gain this little bit of energy, hopefully you can try to use to find answers - not on being upset.
As always, good thoughts from this end. Hope you get some sleep this night.
