I no longer have access to portfolio domain

I had to get rid of my personal adobe account while I am attending a university because they are paying my subscription to Adobe Creative Cloud. When I had my own account, I created a Behance page and website with Adobe Portfolio. I am not sure how I can go about to get the information for these because I cannot remember what login information I used for the account. I need to technically delete both the Behance and the portfolio because I need to create a new one but I am still using the same name that I used previously.
