What Are Renters Rights-black Mold?

I am a tenant and my lease does not expire until March 2008. I have been diagnosed with being exposed to mold. I believe it is coming from where I live, we have an onslaught of knats constantly, even @ exterminating. There is water leaking outside and there is a huge bulge in the downstairs bathroom indicating a leakupstairs. I don't want to have to pay someone to look at it to determine its mold what are my options. I want to move out because I am tired of waking up to a massive headache.
