With regard to fear of fear, the one thing which won't work is trying to think logically about it.
Instead, try thinking these thoughts
"I've felt this way before and survived. I can get through this too"
"Feeling like I can't cope doesnt mean I can't"
I can't predict the future so stop guessing "
"I can't control everything so I don't need to try"
"I'm doing the best I can"
"Its OK to feel anxious and perfectly natural under the circumstances"
My favorite bible passages for help:
Matthew 11: 28-30
There are lots of others
Hope this helps a little. One small step at s time
