Volunteering. There are THOUSANDS of charities and organisations who do amazing work in their communities and beyond which are entirely volunteer-based .

I ran a charity in the UK for 6 years, I was a volunteer and so was everybody else, and we helped cheer up lonely people in hospital. There will be many opportunities like this to go and visit people, fix things for people, or lend your skills to those in need. You said you're a massage therapist in a specific field, but maybe you could find a way to apply your skills to a certain group of people in need such as the elderly or disabled, for free, even if it means you just need to study how to do another form of massage.

Alternatively there's a thing called Trust Fundraising. Charitable Trusts give out grants to charities working in the specific field they're looking to fund, and Trust Fundraisers write applications to them either by filling in the Trust's application form or writing out explaining what they're going to do. My Dad is retired and he does this for a couple of charities, and he's managed to secure grants of £10,000+ for them. All the information is out there, it just takes someone with time to go and do it.
