do you experience lack of ideas/thoughts?

While i'm hypomanic, i feel like i need to do something because i feel so bored if i don't do.

But when i think about what to do ideas comes so fast, like popping into my head but then, they are all gone and i cannot think ANYTHING. My mind literally goes emtpy all of a sudden and that lasts for a while.

For an example i think about what to do and it's like, "i can try to make cold brew, maybe i should look into recipes that i saved. But i have to do my art project, too. Wait, i wanted to learn digital art too, when should i start? What about the article i was writing about the book i read, when should i open the researchs and write it? Should i read that book again to make my article better and fresh? But i was reading another book and i should finish that too, so that i could read the book that i was seeing in everyone's hand for a while. I haven't been playing for a long time to, i need to pull for a character, should i play? I need to organize my bookshelf, i need to organize my clothes. I wanna dye my hair to purple or maybe blue, let's do that but i need to buy bleach. When should i buy bleach? Which one o should do first?"

And then, i end up doing nothing or doing 1-2 tasks that i mentioned cause i cannot decide what to do and when i cannot decide my mind goes empty like all of those ideas never crossed my mind.
