Hi John44,
treat yourself gently, i found with stressful stuff i try hard not to think about the future, just get through the day moment by moment .
I know it's easy for me to say that but it's how i've managed to get through some prity stressful days, like taking my ma to A&E with chest pains.
Time is a great healer, give yourself time to heal .
Bestwishes, M
