Can I be depressed and not know it?

Probably. It's because maybe you are focusing on some other things that you don't even notice you're doing that because of depression.

Of course, when i was 6/7 i knew i felt sad, hopeless, helpless all the time i didn't know what depression meant until i got diagnosed by a medical professional. There is also quizzes online now "depression quiz" but don't take that as a diagnosis i suggest you see a medical professional to officially diagnose you and to get you on the right medication. hope this helped xx take care

Definitely! Depression, just like any illness, can go diagnosed for ages. A lot of people feel like that is how they are "supposed to feel", just like how someone who needs glasses might not realise they do until they try some on.

Yes. You might not want to say you're dealing with depression because of the negative stigma that surrounds mental illness. Thus, you try to rule it out as one of the possibilities

You will know it, depressed and sad are to very different things. You can actually feel depression.

From my past experience, I kept wondering why I felt "funny". It was bothering me of why I lost motivation for things that really made me happy. I noticed I ended up sleeping more and started procrastinating. After talking to friends and family they mentioned I wasn't myself and seemed depressed. So I believe you can be depressed and not know it until others mention that you seem different or feel different yourself.

Yes, it's a new feeling that you're starting to notice. When you do know that you have the symptoms of depression, you should tell someone that way it would be so much easier then going through it alone.

Well yes. You'll be doing something anomal. Like probably sleeping a lot or not going out and being among peeps.

Well, I'd argue yes depending on your knowledge of depression. I had two major depressive episodes without knowing that they were authentic bouts of depression until I got diagnosed later.

yes. some of us are already depressed yet we ourselves didnt noticed it. its when we easily loses our temper. lost the willingness to work or even hard to find happiness.
