Kate - it would appear that you have tried to get back into a normal life at full pelt that you are perhaps not quite ready for. You have gone through heaps physically and emotionally over the last few months.
Recently I put up a post called "What are you doing for your mental health?"
I think that is something you need to give due consideration to.
Good on you for starting out with Ex-med but don't let a parking officer crush you emotionally! Allow extra time to get there so you are not rushed.
Would it be easier to use public transport? I did and that formed part of my incidental exercise as it involved a fair bit of walking both ends but it helped get me in the right frame of mind as I entered the program each time and reminded me of how many strange goings on I have been sheltered from. One day on the train I watched a guy go through the whole process of applying make-up, he was good at it too, and when he was finished he opened up his phone and started watching a movie or something similar which made him laugh and laugh and laugh; it was wonderful to watch someone so comfortable with themselves. Another day I had two people come and sit next to me and start reminiscing about the good old days when they used to knock off Melways and head to the airport and sell them to some of the drivers in the taxi queue. Reminded me that my lifestyle is somewhat sheltered but also heightened my awareness of self and what was around me. And I conquered the mountains of steps at the railway as my fitness was at a low base so it all helped.
Kate gather your thoughts and write yourself a list of what needs doing and another list of what you would like to do and then see what you can delegate and what you can create for yourself.
In our Ex-med group, two dropped out, one had a minor car accident and lost her nerve and the other just couldn't cope as she was squeezing too much into her everyday. Both have been invited to re-apply when they are ready
Take care and as you know there are others on here who feel for you
