sounds like you had some real health problems, i hope you're ok and don't rush it getting back in shape, if it took 8 years to get to that point, without health problems, obviously it will take a little time to get back there, still there's such a thing as muscle memory so if you heal up ok it might not take too long but it's hard to make an estimate. i dont think you should rush things though, take your time and live one day at a time, work with doctors and specialists etc to make sure what you do is in line with their expertise and your previous injuries etc... you're comming of some serious injures there you need to be thankful the outcome wasn't worse... 220lbs isnt bad everything considered.
