No, bipolar disorder is someone who has "hyper" episodes, which is sometimes followed by depressed episodes, but not always. They may even have months or years in between hyper and depressed episodes where they are just "normal".
The "hyper" episodes are what make the diagnoses of bipolar stick. Without the hyper episodes and just the depressive symptoms they will more likely be diagnosed with a depressive disorder.
The hyper eipsodes are incredibly debilitating. I've known a few people with bipolar and it may be one of the most difficult disorders to live with, not because of the depressive symptoms, which like I said before, aren't present in all people with bipolar, but because of the hyperactive episodes.

So when your psy told you "you're a little depressed" it may mean something like you have some "core" symptoms of depression, but lack the ones necessary to call it a pathological problem. After all, being a bit down is part of being human, and there has to be a threshold that determines when something goes from being common among everybody to something that is a pathological disorder that requires extensive therapy.
Does what I wrote make sense to you?

I study psy, so off the bat I'll tell you I don't know everything, but there are somethings I do know. One of them is that certain disorders are known to have a spectrum, autism being the best known one.
That said, all disorders that are well researched have common symptoms and less common ones. Often they also have "core" symptoms. Symptoms without which the disorder will not be accepted as being pathological. Meaning, if you are just busy and don't pay attention often and like to move around a lot, that does not mean it is pathological, or in other words tied to ADHD. You could just be busy, with a lack of motivation and a lot of energy.
To consider it ADHD you have to have something like "hyperfocus", or something else off the "core" symptoms that would make it likely that this is MORE than just a busy kid.
So, the assumptions of psychologist is always that they are talking to someone without any pathological issues and to find IF there's prove against that.

That's what they get for trying to suck out your intestines through your anus.
I love Japanese mythology.

I'm kinda scared of 2017 because 2+0+1+7= 10. The exact number of murders I've commited had I not let that 1 homeless guy go...

BUT, supposedly, Kappas are also obsessed with politeness, and have a little dip on top of their head that's filled with water. If this area loses the water normally in it, the Kappa will die if it doesn't get to water quickly.
Combine this with their obsession with politeness and what you get is a creature that, if you bow deeply to, he will follow your example and basically nearly kill itself as a result.
