How do you know if your depressed?

I've been pretty down lately. I have this constant feeling of sadness. I don't feel like there's anything to look forward to which is stupid coz I'm young and haven't really even gotten started with all the things I want to do. I've never had depression, of felt like this before, I'm always the happy cheery one. Is the way I am right now depression?

I'm sorry you're feeling so down Everyone, feels sad at times but this does that mean you are depressed, but it does mean should see a doctor for a proper evaluation. To feel sad due to the death of a loved one, loss of a job or broken marriage or relationship is normal; if this sadness continues for a long time then it's not normal especially if it interferes with your ability to function. Some signs of clinical depression include: Sleeping too much or too little, loss or increase of appetite, being irritable or restless, feeling tired all the time, cannot concentrate, feeling worthless and hopeless, thoughts of suicide, persistently sad. If you or someone you love is experiencing any of these symptoms, you should get help immediately by calling your doctor or talking to a councellor.
