Hello Wombatus, and a warm welcome to you.
I know what it must feel like to be 10 days out of a MHF, because while you are in there, and (I can say this as I was in a private hospital) the atmosphere is different, there are no phones ringing that you need to answer, 3 meals are provided for you, all you need to do is make your own bed, no cleaning, cooking or washing up and group/single therapy happens every day.
When you do go home then you have to cope with what's been happening before you went in, phones, letters and possibly needing to cook, clean and/or go shopping, so it's adjusting and getting the help you need.
Can I join PamelaR in asking what support you are getting as we are concerned for you.
Best wishes.
Geoff.
