Thanks for the advice WAWed. I feel pretty stuck today...lots of frustration and then it just turned into sorrow, hurt, and sadness. I feel really lonely and empty inside sometimes. It helps to come here, vent and connect with other people who are also trying to find their ways through such difficult times.
I'm going to add one tip to your list that sometimes helps me (I need to use it now): just come back to the next hour or even the next 5 minutes and that's all you have to have a plan for. I get overwhelmed thinking too far ahead...and sometimes even tomorrow is too far ahead for me.
