First - the feeling tha tif something happened to take you away from here - I told my T aobut that - and she said its just because you are tired and sad and thats what I think you are tired and sad.
Dont be angry with yourself - you are doing the best you can - you really are -is there a connection between driving and the feelings? try this - get a piece of paper and write - I am sad and teary at the top - then underneath write WHY? keep writing until you fnd out somthing that explains it e.g.,
I am sad and teary today
Why
I DONT KNOW!
Why
Because I dont want to know
why
Because Im afraid
Why
Because I dont think I can take it
why
Im not saying those are your answers - they are probably mine!!
you just keep drilling down til you get to the reason - may help - just a thought - take care

When you have come to the edge of all light that you know and are about to drop off into the darkness of the unknown,
Faith is knowing One of two things will happen: There will be something solid to stand on or you will be taught to fly.
