So sorry about this, and of a truth, I did got scammed too. I even made a post about it here just the other day, just so to warn the public.
But then, it is well. Sorry about your illness too. I hope you get better soon.
Now, the only thing that can be done is for you to change your keys, if you make use of peakd, just click on the three dots beside your profile settings, it will bring options, click on keys and permissions and then change password. You will need your owner/master key to do that, and all your keys will be changed. Then you can save them in a more safer place, relogin and continue.
