How could I use my financial power in MH recovery?

I have bipolar disorder with substantial assets. I don't feel inspired lending the money to the bank. Any ideas on spending money on my own development? I am 41 and haven't had a job since I was 23. I already have donated to charity. I receive free psychiatric care here in Australia. My psychiatrist says not to worry about getting a job at the moment but focus on developing my social skills. I have a mentor I meet once a week provided for free.
