When you decide with your self, that is your own decision. That comes from you. That comes from your self determination. But the word is mainly used in Japan as a euphemism for suicide. It's kind of important that you know that.
This word is very formal and generally used in historical contexts, such as referencing suicides that occurred during wartime.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.
