Password overload.

Download one of the many free password managers.

I'm wary of keeping all that data online. Something like the old Blackberry available?

If your worry is losing access to your passwords, typically those password managers allow you to export the password list. From there you can just compress the file with zip or rar using encryption where the key is a password that you can easily remember or have written down (and then delete the unencrypted file). Do that regularly and you will have a backup.
