Just about everyone is an attention seeker, I mean the majority of people desire some form of relationships with other people...which requires people paying attention to each other....and everyone wants some of that 'attention'. So yeah thinking of just entirely rejecting that term since its irrelevant and useless and only serves to be used to make people feel guilty for visibly showing upset/sadness/anger/frustration ect.

That said if you feel sad and hopeless most of the time and what not its very likely you could have depression. There are also different severities there are people with depression who on the outside appear pretty functional....also it can fluctuate, like I have depression but the severity changes sometimes its pretty subtle but other times its all consuming misery and makes it hard to even get out of bed.

But yeah if not clinical depression, do you have anything particular going on in life that is bothering you....or lots of unhappiness in your current situation because it is also possible to feel sad and hopeless....for good reason which isn't exactly the same as clinical depression since its a normal response to the situation....but even in that case the situation has to be improved or changed to get rid of that sort of depression.
