My T said to reward good thoughts with positive praise. When you do something good, it is okay to tell yourself that you did a good job. Working on making good habits and rewarding good things that you do can help the worrying. I still have problems worrying, but I know with time it will get better so long as I am vigilante. It is also a VERY good thing to understand what your triggers are and how to address them. Having a plan helps a lot.

Be happy that you are feeling stable! <3333333333333
