I understand mental health plays a big part in everyday life and if she's struggling why doesn't she just be honest, instead of keep over promising and under delivering.
Have a schedule of one video a week and stick to it. That gives her a week to think of video ideas, film it and edit it.
Her edit quality is poor. Chopping and changing scenes. The way she talks about Sean like he's nothing to her. Saying she hates clutter yet constantly buying crap for the sale of it.
If she's going to resell stuff, be up front, do a series or something about it.
She needs to chose a topic and get that right before filming anything for the sake of it and uploading it in a rush. She's losing views because you can tell she doesn't care about her content
