You've had some serious addiction probleems! The only way to get the help you need is seeking a psychiatrist! They can treat your panic attacks and help you cope!

Also just some info about huffing gas! I don't know where you got your info but huffing gas also causes liver damage, cancer, brain damage, neurological disorders, it weakens the heart and a wealth of other serious illnesses associated with many organs! most of these happen years after the huffing! Sleep disorder and anger problems are the least of problems caused by huffing! There's also sudden death associated with huffing as well! So please stay away from huffing anything! Huffing just deprives your cells of oxygen and gives you a couple of minutes of high! The high is derived from lack of oxygen to the brain!

Good luck on your road to recovery!

Try staying busy with exercising and people who aren't addicts! You need friends who are true friends that are willing to help you stay clean!
