Tom’s recovery and support

Our family has been on a journey for the last 20 months since my son Tom was diagnosed with BiPolar Type 1 just after his 21st birthday.
He has been in hospital 5 times since then and we don't seem to be getting anywhere as the local health system does not have the resources to cope with the demand.
To help Tom learn to live with his diagnosis in a safe calm environment I need to take him away from the demands everyday life are placing on him but the last couple of years have drained my resources and I may soon have to sell my house to keep my family together.
I have found a cheap caravan in a caravan park about 2 hours from home (and the friends that are trying to help Tom but are actually making things worse) but I have no money to purchase it and get it set up so I can take Tom there for a few months to get back on track.
I will need to have the funds in the next few weeks as they are once again sending him home from hospital in the next few days and the longer he is in Canberra the more chance there is I will not be able to keep him well.
If I can do this for Tom I am hoping I will be able to offer the caravan to other families in a similar situation.
I appreciate any help anyone can give me.
