If I were you, I'd set aside these letters for a later time. Right now is a bad time to be sending these letters because things are very fragile with the W and getting involved with the ILs may very well make them spew at you since you didn't honor their wish for "last contact". That will not bring you closer to your goal. In fact, it will be a very serious setback for you.
What's important right now is to show consistent actions. When the situation with W and ILs improve much better down the road, then maybe consider sending them the letters.
For now, I'd suggest that you lay low for the time being.
