I've always been a depressed person; most people can't tell until they REALLY get to know me. I have a great sense of humor and function well in society, but inside of my head is a constant battle. Fortunately I don't talk in most of my videos, so it doesn't leak through into my content much. I have another post though mentioning that my mind is so clouded lately I can't even think of things to do for videos lately. I think I haven't uploaded in a month or so because my mind is kind of fried and I don't feel like doing anything. It doesn't help that I have to work 19 days in a row, I'm on day 8 right now lol. 11 days to freedom!
First off, you should address the main issue first before worrying too much about the secondary issue. I finally realized that depression will make you focus on weird things. You need to find why you are depressed, find out how you got there, and find out a plan of action to be happy again.
Just don't pressure yourself, it will bleed through in your content. If you don't have the time or you're not in the mood, don't force it. If you're anything like me, if I forced something through and watched it and wasn't happy with it, I'd just feel even worse about myself and it would cause a chain reaction.
