Stop looking at the negative and start looking at how much you are going to squeeze out of the company, start formulating plans.
If you go back to work and you are not compensated for the damage / reparations, then look at bringing a claim for a breach of duty of care.
If they try to use it as an excuse to get rid of you, then constructive or unfair dismissal.
Key points: Get a diary NOW. Note down *everything* what has happened, that led up to the incident and *everything* that has happened after. No matter how small, *note it down so you dont forget and it builds your case*
Save *every* bit of correspondence relating to it, record conversations on your phone / get a voice recorder and learn how to use it for anything discussed verbally. Soon as you can, transfer those recordings to paper, not as a transcript but as a summary of what was discussed.
No doubt you will have an interview with your boss / HR, make sure to take a work friend as a witness to what was discussed and said and make detailed notes.
Don't be afraid to ask here for advice. You have done nothing wrong and under no circumstances can you be left worse off for it, the law will be on your side, as will we.
It seems you are adverse to confrontation, but time to suck it up and go on the offensive.
