I was diagnosed with bipolar I about two months ago, and I have some questions.

First of all, I am curious if mood swings are a consistent and ongoing thing, or if they generally happen during manic/depressive/mixed states. For me they kind of happen every day all the time, and I'm just curious if that's normal for others with bipolar I

Second of all, I'm curious if others feel like they're really hypersensitive. Things other people say to me or things that happen in my life often have a really strong emotional impact on me, like completely out of proportion to what's happening. Someone taking a short tone with me makes me want to fight, someone showing me kindness makes me want to dedicate my life to them, and someone breaking up with me makes me want to die

I'm really just confused and wondering how much of this is normal for someone with bipolar I, or of there's something else going on that's hidden beneath the manic/depressive alterations
