reclaiming used adopt?

is it possible to reclaim an adopt account I made, that im not sure is connected to my email since it got played a little and returned to me? i really thought I had the password right but it's not working. and since it might not be on my email I dont want to use the forgot password thing to retrieve. idk if I can prove I have rights to the account, but it's very clearly made by me as its related to one of my toons?? this might just be my dumbass mistake losing the proper password but uhm yeah 
I'm also trying NOT to go down a reclaim name method, as i wanna keep the posts that do exist on the account
