I've been having a really hard time balancing my homework and my music and other activities, I'm failing at school because I never have time to get anything completed. how do I keep up good grades!?

Hi, I know that this is a really old picture but I thought I might as well try. All of the sudden I've been really sad. This morning I woke up and my mind started to wander from one scary thing to the next. What if I can't get into college. What if I can't find a husband. What if when I do get married I want a divorce. What if I can't support my kids. I'm really young and I know I shouldn't be worried about these things, but I can't help but think about them. Then my mind wandered to my hopes and dreams. What if you can't become a musician. Then I thought what if that isn't what I want to be. I started questioning everything I thought I knew for a fact. I feel like the world is moving so fast and I'm just staying behind trying to figure everything out. For some reason I feel like I don't belong in my own home. Like I'm meant to be somewhere else. Also I've been feeling like there is an emptiness inside that I don't know how to fill. I'm so confused because I've never felt this way before. It's like I'm being attacked by my own thoughts. I feel like there is something wrong with me. I know this comment is crazy and doesn't really make any sense, but anything helps. I don't expect you to figure this out, so don't feel pressured or anything. Thanks.
