Hi I am just a bit overwhelmed at the moment I have been for the past year. I really high and low moods. Loss of appetite, cant sleep. Violent thoughts. I get distracted easily and cant concentrate can u tell me whats wrong?

Just a bit? "Just a bit" sounds like quite an understatement. You are right at the age when a number of organic psychiatric disorders such as schizophrenia and bipolar disorder appear. You need to see your GP and get a referral to a psychiatrist. Sonner rather than later.
