Catastrophic Thinking and Downward Flow

I was sitting with a friend yesterday who drove me to an emergency eye procedure and was reminded how differently people respond to things. I was worried by this referral that came out of a regular routine check up. As concerning as it was - a small tear in the retina. I framed it as "I am so fortunate that I scheduled the exam. And, this is being held by a Master, the More provided or I created the opportunity to get the appointment."
What I didn't know was my friend had some "bad news" about her eyes a few months ago with a condition which will eventually result in the loss of most of her eyesight. That being said, that was her mother's experience, and she is putting this on herself, not asking for a specialist referral. She is now set up a timeline for having to move, how will she do online banking, that she won't be able to get her groceries, so has to move.
These I think are personal examples of upward flow ( thinking being thankful) and downward flow through catastrophizing ( thinking of the negative impacts and grasping on to them).
I am very aware that my situation could have been a poor outcome and it did worry me that this happened without any symptoms. In faith I know it is part of being in an upward flow, things happen in good timing, the right doctor, the right referral.
I hope the link helps people see how important it is to seek professional help in the way of treating anxiety disorders, depression and so on with cognitive behavioral therapy/counselling and being real with yourself when there is a need for medication.
