Hello Piotr, I am sad for what has happened to you and understand your feelings at the moment.
I can only think that it's not been an easy few years where you lost your friend and now having lost your bike after all your efforts.
I would just take a few weeks of getting yourself into a better place and then remember all the many good weeks you had with your bike.
You mustn't let the world change your smile ( I say this having been guilty of it in the past).
Unfortunately your bike is gone, be it as it was or if you were in an accident, etc. - it's what we have insurance for.
I hope that there will be another bike in need of the care and TLC that you give, that will bring your smile back in the coming months.
It's been a pleasure
