Help Migrating Account?

As a student in middle school, I created this khan academy account using my district-provided school email. As a senior in high school I have now learned that these email accounts get disabled upon the student's graduation/exit from the district. I have put many hours into khan academy on this account and would like to keep all of my stats and progress here. Is there a way I can change the email I used to sign up to this account with? I couldn't find any way to be able to contact a support team so I am just posting here in the community forum for now.
