I have chronic sleep deprivation (10 years sleep debt) due working all night long for 10 years and sleeping few hours per day, my health is affected by this, how can i recover from such a long sleep loss?

The “debt” is not really important. You just need to fix your sleep cycle today so that you can work on improving your health going forwards. Please speak with a doctor physically or by telemedicine to discuss options to improving sleep.

You would likely fit the category of "Shift Work Sleep Disorder", which can be managed with specific medications. Find a neurologist or a sleep specialist (maybe a pulmonologist), and get your sleep back on track.
