Feeling at a loss of ideas can suck a ton. I would say that you could brainstorm daily for a few minutes to try and get more ideas.
Revisit old videos and add a twist or updated opinion on something, think about what happened during the year that you could reenact (then think smaller like month, week and day)
Do a trend video of something you like, if any of the trends appeal to you, show off a local landmark that people would find interesting, walk us through a day in your life, and brainstorm some more while you edit and upload.
Put your ideas down on paper or in a document and continue to update it. Cross off the ones you have done, color code those you can /need to revisit and soon you'll find yourself never losing your ideas again.
This is just some of what's helped me.
