Hi there! Welcome to PC.

kindachaotic is right, everyone experiences bipolar differently. Also, your symptoms can change as you get older. Medications also effect everyone differently, so if you're not having side effects that is more of a blessing than something to worry about. I had to go off of Lamictle because I got a rash in the first three weeks, and that's dangerous.

Not everyone has rapid cycling. You may never have it. Basically rapid cycling is at least 4 cycles a year (2 depressed, 2 manic.) But some people only experience one manic episode in their entire life and then only deal with the depressed side. Hypomania is less sever than mania, and that's more a of a doctor question.

Obsession is like "Did I turn the stove off? I didn't turn it off. What if I didn't turn it off! I can't remember if I turned it off. What if the house blows up. Maybe I should go home and check that it's turned off. I have to turn the stove off. etc." Over and over and you can't get anything done because one thing is completely taking all your focus. (At least that's how it is for me.) This is just an example, you can obsess about anything.

I also have generalized anxiety disorder, so if you're concerned abot your anxiety tell your doctor.

Vitamin D is good for you in general, but only about 15 minutes of sunlight without sunscreen is safest from what I've read. But discuss that with your doctor.

Leading statement.... yeah, "I feel like hell is about to break loose in my head." That would be mine. I get pressure in my head and I don't feel well right before I drop into a mixed state. But, I have been diagnosed with mixed states and ultra-rapid cycling, so that's just me.

It is a blessing to not have suicidal ideation. You don't want that demon, I can tell you that.

These are all great questions for your doctor.
