Inhalants
Okay, Now this is a different story. Since I've never done anything like this, I got some views from someone who has done this stuff before.
They said it was fun at the time but then they got into a lot of trouble. They were failing everything in school. Their parents didn't know what was going on with them. And it made them more depressed.
Inhalants are very dangerous to your senses, and your brain, not to bring up the fact that everytime you do it it kills more and more of your brain and sooner or later you'll end up living in a mental hospital. Now that can't be too fun.
But, There are ways you can stop this. The best way is to seek help from a professional doctor. One that can help you quit and probably give you something to build you brain back together so you can actually get out of the 11th grade and move up to the 12th.
Although these things seem fun, no one has any idea of what they are putting themselves through. If it's to stop depression, that's the wrong way to go. It will most likely take you deep into it.
So get help while it's not too late.And it's never to late, so save your life.
