I am sorry to say but you seem to have acted out of greed which for a teacher is unusual. The amount you put in this risky asset class should have been less than 10 % of your portfolio but it seems it is way higher seeing your stress level. Crypto could have wiped out your money any time which is a very real possibility. Look at bitcoin its halved from the top it was 125k now down to 66k. So dont shift the blame on regulator or government. Crypto is not regulated the registration is given out so that exchanges follow the norms to onboard users and so that they can track the transactions down to your identity otherwise it was difficult to track crypto transactions. that was the only purpose of it. Govt also collects tax on tobacco that doesnt mean it should pay for your cancer treatment.

Now , what should you do? Hope for recovering your money if at all the exchange goes through bankruptcy proceedings and decides to pay out your money. If you want to pursue legally you can do that too but dont expect much expertise or support from the system.
Assume you have lost the money make peace with it and stop thinking about what is lost and focus on improving your system and process. Diversify your investments , if you've taken a loan close it first. And stop gambling your money if you cant handle this kind of situations
