Do meditation or chanting make one less agitated?

Understand that meditation helps to calm one's mind and does it also helps one get less agitated and less affected towards the unnecessary? What about chanting? Does it also have the same effect? If one is patient and he/she naturally will not get frustrated easily and not easily irritated by minor stuffs. That does not mean he/she meditated or chanted to achieve such state of mind? I'm actually asking for myself. I'm not much of a patience person, short-tempered at times. I don't meditate but i do brief chanting occasionally. I used to do chanting when I was little and looking back, I feel like life was a little better back then and possibly less frustrated, not sure if it has anything to do with chanting. Growing up, I felt as if life was so injustice and merciless and often got angry at myself and things around me. Probably I care too much, i'm not sure. Things may not get on somebody else nerve but to me, it was so easy! At work, at home, my surrounding, everything just seems so tough on me. So I don't know what helps.
