(I) don't need this
1. An expression of frustration when something bad happens. Ugh, a traffic jam? I really don't need this, I'm already running late!
2. An expression of one's unwillingness to tolerate something. I don't need this kind of mistreatment—I'll just take my dry cleaning somewhere else!
I don't need this
I have enough problems, and I don't need another one. Please don't tell me we just lost Internet. I really don't need this right now. You know, Jerry, I don't need this. So if you're going to keep treating me this way, I'm just going to stop helping you.
