I feel empty

What you're experiencing is common with depression. I am not a health professional, so don't take my word for any of this, but I have depression.  It sounds like how I feel when it gets really bad. 

What you should do is find a doctor who listens to you and can put you on the correct treatment path.  Maybe I'm wrong and it's not depression, but only a doctor can figure that out. 

Don't blame yourself about any of this. Depression, or it's evil twin anxiety, are really reasonable reactions to today's world, especially when you're in a minority group or other vulnerable identity, such as being queer or alt when it's against your cultures status quo. 

That being said, there are things you can do. Even if you don't enjoy them at first. If you expose yourself to sunlight for around 10 minutes, you make vitamin D which is said to help. You can also run around only until you would say it's a little harder to catch your breath, or until your legs get tired. These help when I don't want to do anything and I can't find my joy. 

I want you to start feeling better when you can. Using every tool in your reach is better than not trying, and I know how difficult it feels. I have been all the way to the edge of the abyss, about to jump in. Just keep fighting, I promise you'll come out the other side with less rocks on your back. 

Try new things, ask yourself why do you feel the way you feel, do journaling, reduce your time on social media, try different forms of expression like drawing or poetry... This are general pieces of advice that helped me in my experience, but everyone is different and it is important to talk about this things with a mental health professional. Take care of yourself, I hope you feel better in the future
