Your post is a bit difficult to read to clearly understand your issue. Correct me if I am wrong, but it sounds like you were using someone's account on your TV. If it is your account, you could attempt to log into your account via a computer and you may be able to see your stuff that way, unless you have an app/channel that requires a specific device type, where you can only view on specific devices (such as Roku only).
If you can't access that account because you don't have the log in information or that account belongs to someone else and you no longer have access, there is not much you can do. All of that stuff is saved on the cloud and not on the TV or your phone, unless you saved files to a hard drive or something. Even if you got a new TV/streaming device, you would need the account information to be able to have access to the same shows/apps you did before unless they were free. You could still view free channels without the TV, via a computer in most cases though.
I would recommend keeping that person away from any fragile electronics in the future.
