Can't do much with iPod Touch due to iCloud

A while back, I changed service providers, changing my e-mail from n******@mts.net to n*******1@shaw.ca (Because the 1st one stopped working), unfortunately, at the time I did not switch accounts and I have since forgotten the password to the first account. Problem is, my iPod, which I want to reset is connected to my first account and I cannot do anything with it. It is this glorious paperweight that I can't update, install or download apps etc..... What can I do to fix this problem, because iCloud has completely screwed it up. What can I do to fix my problem?

iPod Touch (5th Generation, 9.1)
