I'd probably get the same way if someone with little knowledge on a subject I know more about kept lecturing me -- and then told me how to raise my kid. I'd have been arguing the whole time.
I get agitated over big things, small things, and sometimes it just comes out of the blue and I feel itchy inside (itchy's the only way I can describe it, I'm not leaving off the "b"

) and realize I'm getting agitated, but there's no apparent reason for it.
My hands don't shake but I get restless and bounce my legs a lot. I'll try to focus my atention on something else if I can but it's frequently futile. I generally have to drown things out in some way (music helps) to bring myself down. If I can't, I take a Xanax.
My boyfriend and I have had some real special fights over dumb **** because of my agitation (heated, heated arguments over World of Warcraft where I'm so frustrated I'm almost crying, for example). Idk how he puts up with me sometimes, but I'm lucky. Unless he tells me to take another dose of my meds. Then it's rage/crying time.
