I have posted here before asking people if what I have sounds like bipolar. Answerers and a friend who I told have said it sounds like bipolar. I know I can't get a diagnosis online but I wanted to see what others thought before speaking to anyone like a counselor. The people here insisted that I see a doctor, and others telling me specifically what they think I have (Bipolar II, after looking it up it does seem so much like me)

But here's my question;
I go through the depressed and happy stages (possibly depression and hypomania) but also go through stages where I feel both empty and great at the same time ( it's hard to explain, and I'm not going to bother trying) and through stages where I feel 'normal', as in what I feel feels 'right' and seemingly what other people feel/how they act.

But when I'm in a period of normal mood or sometimes even a mixed mood, I sometimes forget how bad the other moods are. Like, I think back and think I'm just overreacting or it's normal. These normal or mixed moods usually don't last very long , and the majority of my mood is at the depressed side... And when my mood crashes back down I realize again how back the feeling is.
The reason why this is a problem is if I am to go and speak to someone about this, I want to go when I'm in a normal mood, because It would be easier to talk to someone and I'm more focused and open, and not one sided. But if I think this way while I'm in a normal mood how can I bring myself to get help? And how am I supposed to give accurate information if it all seems 'distant' ?

Anyone on here with bipolar or knowledge of bipolar can you please let me know if this a normal frame of mind for someone with bipolar?

Also, only recently have I been thinking i could have bipolar.
For a few years (3, maybe?) I'd been thinking I suffered from depression. But the thing was, I'd go through times where I don't feel depressed, some times actually being genuinely 'over the moon'. I was so busy looking at each individual detail (feeling depressed *full stop* feeling okay *full stop* feeling great *full stop*, never putting the sentences together)
I recently took a step back at looked at the big picture, and put it all together. Is this normal for a *possible* bipolar sufferer? If you don't understand this question don't worry about it, I'm more here for the first part, just thought i'd add this in while i'm here.

Thanks in advance.
