I admired the fact that you only lost some of your hope and optimism, and only for a few seconds. In your own words, you think the program is helping, and you’re toughing it out, while remaining optimistic about the next person to work with.
The fact that you ended your post, stating you’re only venting is a healthy sign, along with the favourable medical test results, and that could help break cycle we get drawn into, of perpetuating uneasiness of our perceived symptoms when they are less than the results state they are.
Like good software designed products, you sound like you’re “robust” and dealing with a minor “glitch”...we have a lot more going for us than software though, shown by your vulnerable side with the two birds building a nest.
