Are you always like this or is it a recent symptom? If it's recent and part of a manic episode then you won't be able to control it without intervention- therapy/medication adjustment. I just had an episode myself and irritability and agitation were a huge part of it. I had not had this as a symptom before, at least not this bad and I could NOT control it on my own. I'm over it now thanks to meds and thank god because relationships can be ruined during this phase. I feel for you!
