Buzzing head

I hate those meetings where confusion reigns. Those where who wants to take the floor does it in a screaming manner, and those who do not dare to address the audience chat amongst themselves.
My brain is not designed to withstand this. Neither are my ears neither.
When I go back home after such a meetings I feel my head buzzing for hours, like a hive packed with bees. And I feel nervous.
This is why having a cat at home might help in these cases. A nice cat purring and lying with you on the bed is so relaxing. Yes, definitely it would help a lot, unless you have an aggressive and surly cat like mine. I can't ask her to make me feel better.
Usually I am still nervous and I just go to the bed. Alone, with a thousand bees buzzing around my temples.

Great job! Especially with all of the metaphors and similies, it really helps with the imagery. Just a few grammatical mistakes, but your English is really good! Keep improving it and you'll be set!
