Could this be depression or something else?

hi. I am a male 21 years of age. I was wondering if this could be depression or some other mental disorder. Some days I feel very sad and other days I feel fine, but it seems to always happen a lot lately. It got to the point where life seemed boring to me and I am concern about it. Can anyone tell me if its depression or bipolar or something. Thanks.

The test for depression is as follows: Listless. Don't want to get out of bed. Want to sleep all of the time. Nothing turns you on. Crying. Everything, including simple things, are very difficult to do. Constant bad thoughts....no happiness. Appetite diminished. Don't want to associate with people. Life is very difficult. deep depression...thoughts of death. Bipolar is a two way street. First there is depression as mentioned above. Next after a period of time you swing to a manic mode. You get hyper. You want to keep going all the time. No time for sleep. You go out a lot and socialize. You begin to speak loudly and rapidly. Complete personality change from what you are normally (except depression). If you seem to have these symptoms you should see a psychiatrist. There is medication for either depression or bipolar.

most likely bipolar, talk to your docter he would help you way more than i can
You know we all have good and bad days.I know there are some test on line to take and see if you are depressed..Whether or not go see you DR.

it could be depression, it could be bi-polar, it could just be that you are a teenager. it wouldn't hurt to talk to someone who could test you and sort that out.
I think it could be that you're moody.
