hi rach, thanks for your post. i am having a similar thing happening. my mom is gravely ill and will probably die soon. i have noticed that certain anxieties i have had the past few weeks no longer seem like that big a deal. it seems to change from day to day, depending on what else is happening that day.
i agree with other posters - i think you are probably getting better at dealing with anxiety - the ones you know about. if confronted on a regular basis, they tend to become easier to deal with, or to ignore completely.
