Depression can be experienced in many ways. So, your mom's experience with depression while very different from you own, doesn't mean you're symptoms are not depression or that you have bipolar disorder.

As for whether or not it is bipolar, doesn't matter. Just go along with whatever treatment plan you have and see what happens. Even with a bipolar label you end up trying dozens of drugs to the point where it doesn't matter what they call it, you'll realize they're just guessing.

As for your symptoms, yes, I've experienced them.
