Great picture. One to print and hang facing out the front window! On the other note, best advise I ever had during my psy training days was this:
The mind can only hold one thought at a time. It can of course switch back and forth rather quickly. These issues are of course, important and need appropriate time for thought. However, excessive worry and ruminating does nothing but drain the mind and body of energy. Assign and allow yourself appropriate restricted time to contemplate the issue (one at a time) that may be: I am going to think about this (and worry if needed) from 3:00 - 3:15. (less is better, repeat thought time morning and evening or each day if needed. Don't try to ignore it, because that just doesn't work, the subconscious will keep reminding you and bringing it up unless/until you have addressed it or scheduled the time to address it because it is important. You don't have to solve it in one session, just honoring the time to process and then put it away to next scheduled time will suffice to help quiet the subconscious mind.

Then commit yourself to thinking about other positive things. Work to shift your focus from the worry time to focusing on plans for "after", how/where you'll go to dinner after the surgery. What things you'll be able to do or do again after the surgery, etc. Think and discuss/dream about those things in detail. What the food will taste like, what the views will look like, what the smell of the salt air may be like. It takes some practice, but the more you do it, the more it will become habit and train your mind to let go while still paying attention and honoring those things that need it.

Best to you all.
