Not to sound glib, but it sounds like you need to work on your business model. Soma has been 'in business' as a community supported operation for over 10 years now. They have the occasional shortfall, wherein they blast to the community and usually make it up.
It should probably be pointed out that they have more than one employee, and donations aren't their only source of revenue, and they're still able to operate their service without commercials, which would ordinarily be their entire source of funding. Simply put, they've found their business model in spades, and if they absolutely had to, I'm sure they could fall back to a commercial-supported endeavor, though I don't know if they would be willing to.
I'm sorry for you and your situation, but I don't see any reason that should begrudge you their continued success.
