How to vent so that others can understand me?

Well, I am not asking this for a pity party or anything. But the people close to me don't understand accounting and taxes, so when I need to vent and rant, they don't understand the language that I am speaking. So needless to say when I am done ranting and venting I do not feel relieved, rather I feel like I am complianing about something that they can not help with. I don't need or want their help, that is just the feeling that I get.
