Has anyone experienced a delayed anger that showed up later in life?

Hey all, I have found that as I have gotten older, I have become more angry about things that occured when I was in my childhood and teenage years such as abusive home life. I seemed to be ok with alot of stuff until I hit my early 20s and then I started to experience alot of the pent up anger and frustration. If anyone watched the Oprah show recently when Sinead O' Connor was on talking about her depression then you'll know more about what I am talking about.
