Help Lis in this crisis

UPDATE: The plumber has come, and the tenant's boiler needs to be replaced urgently. It is currently  a hazard. I'm now a complete, quivering wreck.

I'm in a major fix. I don't have an income right now, but I do have some major expenses. The tenant's apartment has no heat, and a leaky kitchen sink, and needs a plumber. I have outstanding gas,and electric bills, and water bills for both apartments. I'm looking for work and trying to hold things together, but I'm desperate and need some breathing space. Help!
