Bipolar II vs Cyclothymia depression

Ok, I asked my psychiatrist todsy about my diagnosis, and she looked undecided, then said cyclothymia, that it's an irregular and unstable disorder.
I don't like questioning things but....I think it's bipolar II. Basically, I see cyclothymia as a mild subtype of bipolar II (at least from what I understand from reading about the two). The only thing that changes is that in cyclothymia, depression is mild or moderate.
Well, I don't think my depression is mild or moderate. It depends on the phases. I usually get short severe depression phases or long mild to moderate depression phases. So maybe it fluctuates between bipolar II and cyclothymia?
She said it's unstable, characterized by cyclic mood swings.
Maybe I am missing the difference here but from what I know, cyclothymia is when depression doesn't get severe. But what is the difference severe depression and moderate depression?
To me, severe depression is when I cry and feel like I want to die (but I dob't attempt suicide), don't want to go out and feel like my life is over.
Moderate and mild is just when I'm depressed but still have the strength to think in a more relaxed way, kinda like trying to reassure myself.
When my depression is severe, I don't reassure myself....I just can't do that.

But this month was weird. I didn't cry or had violent negative thoughts, but I feel like this phase is consuming me now. Moderate or severe?
I can't go out and don't want to see anyone. I stay in my room all day and barely get out of it to eat or go to the bathroom.

So, what's the thin line between bipolar II and cyclothymia?

p.s: I don't want to talk to my doctor about it and sound like I'm questioning her, but I will try to explain deprrssive phases in a more detailed way.

Do you have distinct hypomanic phases as well? I hear you talking a lot about the depressive phases in your post, but not much about the other side. I think this would be good to talk to your doctor about. Don't feel bad about questioning, I think it's good to have an open and honest discussion about what your thoughts and questions are. You deserve to have a greater understanding of where she is coming from and why. This could help you to also gain a greater understanding of what is going on for you.

Yes I have distinct hypomanic phases too. I don't talk about them much because they are less frequent and milder than depressive phases, and only last a few days, that means, less than one week. They generally occur after depressive phases, and they include fantasies of grandeur, elevated mood, extreme optimistic views about my life and the world, restlessness and fast speech and faster racing thoughts.
I will he discussing about depression with my doctor and for this, I prepared a paper because writing allows me to be precise and express myself in much better ways.

Another thing I will discuss with my doctor about the possibility of a second type of hypomania, that presents irritability, racing thoughts and aggression.

Since I am highly unstable and unpredictable it is very hard to fully understand what's going on and prevent it.

She described the nature of my phases as cyclothymic, but she didn't say my depression is just mild. I know it's not, and hopefully that paper I wrote will help both of us, clarifying the features of my depressive phases.
I have observed two different types of depression, which differ in intensity and length.
Violent severe depressive phases lasting a few days (from 3 to one week) and longer depressive phases that are of moderate intensity.

However, the highly unstable nature of my disorder (and possible borderline traits I am observing) makes it very difficult to be precise about the various phases.
I had like two or three distinct hypomanic episodes in 7 months. Distinct means that they could be easily recognized.

On medication, hypomania seems to be gone, but depression is still here so after telling my doctor about it she decided to add an antidepressant in order to help me fight depression.
But Lamictal definitely made me more stable and less inclined to get hypomanic, and it also made my depressive phases milder. Before medication, depressive phases were usuually short and violent. Before medicarion I also experienced one month of milder depression.
This is what makes me believe that two distinct types of depression are present in me, while hypomania seems to always be the same.
But I am not sure whether that persistent period of aggressive and irritable mood I had a few months ago was another face of hypomania or something related to possible borderline traits.

Ah, everything is so damn complicated
