Am I really bipolar?

Any and all advise is welcome, I am very confused and have been for quite some time. I was diagnosed bipolar II a little over a year ago but I've never been certain it was a true diagnosis. Ive had around 7 doctors in the last 3 years (they all would leave their practice for another one) so I havent had a doctor that really knows me. Ive dealt with depression and anxiety since i was around 10 years old and my family has a long history of undiagnosed mental illness so I'm not sure if anything has been passed down, but since that was "normal" for my family I never seeked help until I was 18 years old. I'd been very depressed up until about 6 months ago (was very depressed for a little over 2 years) and didn't experience mania or mood swings really which is why I'm hesitant to agree with the bipolar diagnosis. But 3 months ago I went off lamictal and felt fine for 2 months and then recently this month I had some extreme mood swings from blinding rage, to exhaustion and depression for no reason at all as well as having very grotesque dreams. Some nights I couldn't sleep more than a few hours because I was so worked up about things. Went back on lamictal and I feel normal again. I now believe I do need a mood stabilizer, but I'm still unsure if I'm actually bipolar. I have ADHD as well, I don't know if that has anything to do with my inability to sleep. Is is possible to need a mood stabilizer but not be bipolar or am I just in complete denial?

Of course, none of us can confirm.
I am BP2. You don't seem to have the hypomania I have, but we are all different. If you only have the depression, and none of the fun of hypomania, that sucks!
Given that you never have the hypomania, I wonder if you are just depressed. Regardless, I wish you the best. Mental illnesses really suck.

For me that raging anger is me being manic. It's not nice at all anymore. I feel like I have electricity inside me, no happiness, just kind of angry numbness. BP 1 here.
