Can I still sue my former workplace 9 months after mold exposure and severe onset of mold allergies and severe asthma?

Basically, I got sick where I worked. There was an obvious moisture problem and brought to management's attention. I was ignored and I kept getting sicker. I suspected it was a mold allergy. Suggested professional testing and was only allergic severely to mold. I also developed severe asthma. I got so sick just being in the building I had to take a day off. I have been unemployed since December 30th 2013. Now I continue to suffer from exposure to mold when outside for even menial amounts of time. I was never this sensitive until exposure at work. I have medical bills I cannot pay, lost wages I can't get back and I am on a host of medications for severe allergies and severe asthma that I suggest to pay for monthly just so I can breathe. Is it too late to file for any compensation as I really thought by now I would be more improved? I need income but am so disabled when the mold counts outside are low moderate to very severely high I can't work. I am also suffering from ringing in the ears, balance problems, memory loss, hearing loss, and other issues that I never dealt with until exposure to mold in the workplace. Any suggestions or help would be greatly appreciated! Thank you for your time.
