Hi,
I have a short text, I need to fill the gaps but my english grammar sucks

I would be very grateful if someone try to help me!
The text:
If you’re having problems with a difficult boss, first of all you need to talk ..1.. him/ her. He/ She may not know you are having trouble. By putting ..2.. such a meeting while bottling ..3.. your feelings, you could be taken ..4.. an irrational person when you finally confront him/ her. No one, ..5.. of all management, wants to listen to hysterical complaints.I think the first (1) is "
to" but I'm not sure

I appreciate any help! thank you very much!
