forgot sudo password- cannot login as root- cannot login to phpmyadmi

So this is embarrassing but… A month ago I set up a basic LAMP following your tutorials, upload a web app I am working on and all was well. Last month been programming and uploading sporatic update but not really testing the live site. Recently noticed some problems, deleted the public_html directory (sorry not using git or anything yet). Now wanted to log in to phpmyadmin to check the database but could not login, although I have my password written down here. I was thinking of just reinstalling phpmyadmin but my sudo password fails and I have that written down. When I log in to the droplet console I also cannot login to the droplet. I must have confused passwords or something during the setup process. I do not think I ever got a password emailed to me because I cannot find any email at all from do and I ssh with a key. Is there any suggestions or do I need to destroy the droplet and start again.
