I feel like such a failure

Just have to get a vent out here. It feels like nowhere in the entire globe will be able to understand what we go through. There’s days where I just shut down; I feel my body using all its energy just to breathe as my chest gets tighter. My limbs feel like they’re made of bricks and all I want to do is just curl up and cry. I can’t believe nobody thought anything was wrong for so long. I was late most days to school because waking me up would genuinely be impossible, like you could pick me up and throw me against a wall and I still would be dead asleep. Not even passing out in school was enough of a warning, or having to wear 7 layers of clothing to stay warm in 60 degrees weather. I failed high school. Now I stream video games to people, and I can’t even do that sometimes because I’m too tired. I’m also an artist, and I can’t even move my hand to draw sometimes. It gets really hard to go on some days, especially when nobody takes it seriously. How do you even make it past 30 like this? How do I get anywhere in life? How do you even hold friendships when you hardly have the energy to breathe? My eye sting. I’m going to bed.
