I slept and fell in a puddle of water at quest diagnostics and I stay on the second floor and I can barely get up there.

Evidence: 

Did you notice any surveillance/ security cameras nearby where you slipped?  Having a witness is very important, but this witness appeared after the fact (at least that's what it looks like).  

Insurance Claim:

Have you opened a claim with Quest and/or the property management for the building?  Their insurance carrier will need to investigate the length of time that the liquid (assuming it's water) was there and whether there was a premise liability policy in place and/or whether it was followed.  

Treatment:

What about treatment?  Have you seen your primary care doctor?  Have you made notes or documented your pain, mobility, disturbance to daily activities?  

These are among the most important "First Things" you should be doing.  

If you cannot safely reach your room or needed medical care, notify respite staff or its on-call supervisor immediately and use emergency services for an emergency. Put a written request to the respite program for an accessible placement or another reasonable modification or alternative that permits continued care, and keep its response. That disruption sounds especially difficult. Depending on the operator, disability-access laws may require reasonable modifications unless this would fundamentally alter the program. For the fall, a California business must use ordinary care. A puddle alone does not establish responsibility: evidence ordinarily must show that Quest created it, knew of it, or reasonably should have found and corrected it, and that it caused compensable harm. The nurse’s identity and photographs may be important. Promptly preserve names, date and time, footwear, condition and location of the water, photos, medical and respite records, bills, and all communications. Ask in writing that Quest preserve surveillance footage, photographs, and any incident report. A negligence lawsuit is generally due within two years of injury. If a public entity may be involved, a government claim normally must be presented within six months, so do not assume the two-year period applies. Deadlines and exceptions can be fact-specific.
