Hello! Great examples — you’re using “jump on me” correctly ✅. 📌 Jump on (someone) = criticize, attack verbally, or react angrily. “Why are you always jumping on me for being late?” 📌 Get on my case = very similar meaning, but it’s more informal and American in style. “Stop getting on my case about homework!” So yes — you can say: “Why are you forever jumping on me for such unimportant things?” (slightly stronger, feels like a sudden attack) “Why are you always getting on my case about unimportant things?” (more casual, everyday speech). 👉 Quick tip: “Jump on me” = feels more intense. “Get on my case” = feels more conversational. ⚡ Homework: Try writing 2–3 sentences where you swap one phrase for the other and see how the feeling changes.

"get(ting) on my case" sounds fine, an alternative would be "bothering me". "jump on me" sounds a little wierd.
