I lost my email account and need to access the board, how I can I change it for my new one?

[Maria Eduarda Alberici Putton]

I used to have a work paid email but I lost access to (did not renovate) and I lost my account on Trello. How can I change (the old email for my regular one) without lose my whole board and work on Trello? 

My whole life is in there!
