Why is it this way?

The past couple of weeks, I have had some difficulty doing the things I love to do. I LOVE to sing, but I haven't done much of that recently. A couple of months ago, I started my own YouTube channel and I love it. I also became interested in writing on an app called Wattpad, but these past couple of weeks, I can't bring myself to do much with the things I love to do. I don't express much of my feelings with my family, because every time I do they try to dismiss it as my imagination, or stress. Which is true I do get very stressed over things, but this is different. I just don't feel motivated to do anything. I can hardly get myself to clean my room, despite the fact that it looks like a war zone and if I were to get up in the middle of the night, I would probably fall and break my neck. The only reason I'm even writing this is because this is the only place I feel that people won't berate me for what I'm feeling or try to explain it away.
