こんにちは。＆ おやすみなさい。 「状態」condition (could be used as health/mental condition, or any kind of state) 「事態」situation (especially used as a bad situation.) [This word is often used with "陥る（おちいる）” e.g. "状態に陥る" does mean goes/becomes into a bad situation] 「状況」situation (whether bad or good, it is used as a situation)

I think jyoutai and jitai are almost the same. But jitai sounds more serious and unwanted situations. jyoukyou seems to be more related to the flow of time.
