Even though this is from 2016, I'll answer. You're probably a teen or adult by now!
This sort of thing happens to me all the time, and it's normal for people with depression. You're not the only one who went through stuff like this.
A huge piece of advice is to act like you're feeling better until you actually do. Even if you don't enjoy your hobbies or activities anymore, still do them. By telling yourself over and over mentally that you're feeling better and doing the things you love, hopefully that will help. Of course, I'd also like to believe everything is resolved by now.
