My heart goes out to you my friend and to your Father. I understand how you are feeling. I am very proud of you for working on the CBT and keep it up as you will need to be strong for your Father but also you need to work through every moment of anxiety for your own well being.
It won't be long and you will be back home so lean on us my dear Ben and know we are here. You can always come here to vent your fears and anxiety and sharing what you are doing to fight back is awesome.
Gentle Hugs to youKitt
Ben i am SO sorry. I have watched my favourite aunt battle Parkinsons for years. I pray that you are all able to come to terms with what is happening and that your dad gets the absolute best medical care possible.
Thinking of you at this time,
