Pip mandatory reconsideration

I don't think I have written this right.
First point of getting about I scored 4 points as they said I could walk further than I can. I have heart condition and later in year will have open heart surgery. Fact.. gp clarified this with I can't walk far.
2nd point is I also have an anxiety condition. Gp clarified this.
I was informing them of my conditions. In my mind I should have got enhanced mobility as 1, I can hardly move and 2, I have an extreme anxiety disorder and to undertake journey on own would cause extreme distress.
If I did not have heart condition then I still could not go out alone and if I did not have anxiety I could not get about due to heart condition
