One of the hardest things about YouTube is that it's entirely self-driven - you have to fund yourself, push yourself, and at the end of the day you're the only person you really to answer to if you haven't made a video. Which can be stressful. But also liberating, really. If you're feeling lost it might be a good idea to take a break and not put too much pressure on yourself to have ideas.
Whenever I get writer's block or feel completely uncreative I take a step back and breathe. Usually when you stop feeling pressure to create the ideas will slowly start to flow back to you

It can also be nice to take a month or so just to consume (not food, lol) but other people's content. Watch the top youtubers and analyse their structure, read every random article on wikihow and imagine how you'd turn it into a video, watch people doing what you do in your videos on other forms of media (radio, TV, film).
And hopefully all the other life stuff will start to feel a bit more manageable if you take the pressure off yourself about YouTube - if in doubt just break it all down to really small steps and concentrate on one thing at a time.
