I think it's hard, when you have years of NOT expressing your opinion, of being bulldozed or suffering in silence, to use your voice to express your concern or pleasure and NOT think of yourself as being obnoxious.

We don't have experience in having others hear our opinions.

I used to hold things in until I was furious, so people always saw me as angry or defensive. But after a few months of therapy, I could sense discomfort inside AND know that I needed to address it immediately and not let it fester into an anger bomb.

So, in a brainstorming discussion I'd say "Perhaps you don't realize it, but you've been making a face each time I speak and not writing up my contribution".
Before, I'd have let it go, been angry for weeks and not wanted to help with the planned changes because my voice was not heard.
Now, the recorder looked momentarily offended but she started to write up everyone's contributions. No one else thought I was obnoxious (I asked later), I was told, of course you said it, it was happening.
