Oh no! (Denise's knee surgery)

I hate like hell to have to do this. I've been in a lot of pain with trouble walking for past couple months. This makes doing my job more difficult 'cuz I walk around on concrete all day. Finally had an MRI and my doctor told me I need a partial knee replacement. Whaaat?!? Well, I really can't afford that 'cuz it's about $6000.  Plus, I have crappy insurance. My deductible of $1500 has been met (thank you!) and I'm responsible for 30% of everything else: Dr, facility, anesthesia, etc.  So that's about $3300, which was my goal, but I've reduced it to $2000 to make it a little more attainable. Pre-op is June 10th and then surgery will be scheduled...but I'm still a wee shy of my goal.
ANY amount is definitely helpful.  (terrible timing, I know)
I really can't thank you enough.
