Well, it depends. From what I remember of your ASMR videos, you're working indoors in a fairly tight space. I believe that the 35mm lens would serve you better than a 50mm. Trust me, I love the 50! But, indoors you'll have to place the camera further way to get a similar field of view as you current setup. If you have a big enough room, then fine, but if not a 24mm, 28mm, or 35mm might be much better for your situation.
Why?
The 50mm will be much more flattering to your face. It's a better "everyday life" lens, but the 35mm is right up there with it. Most street photography is done with a 35mm lens. 50mm is fairly close to what the human eye sees. (40mm is what the human eyes sees if I remember correctly.) Many movies you've seen were shot entirely on 50mm lenses. You know the look, you just didn't know it was called a 50mm lens.
Also don't forget vintage lenses, although adapting vintage glass to Canon EF mount in more difficult than other mounts.
I use a Canon FD 1.8. It's the same lens it was just made back in the 1970s, but I use it mostly as a b-roll/cutway a lens. I would have to place the camera something like 5 feet away from me to get the framing I'd want. That would place the microphone out of reach. So I use the Canon FD 24mm when I'm doing interview portion of my videos.
For vlogging I'd rather have something between the 24 and the 50. How much of the background do you want in the image vs. just your face? That's what it comes down to.
Here's a good example:

Notice the shorter the focal length the more anorexic the models look. The longer the focal length the more flattering the image.
