What's does this mean? ' I'm feeling really mean today' Is that felling ill or feeling interesting? thank you!

Learning languages is fun! Hi everyone, my name is Jen. I’d like to talk something about English. Our people learning English very early, but I think our English education more concentrate on grammar and test instead of talking. Sadly, We don't have much chance to speak English with native speakers. So generally speaking, our students are not good at talking English include of me. I'm interesting in English and western culture. Especially British English. Of course American English is also great but I think the way British pronounce is easier than American one for me. For instance, in Mandarin we don’t have much ‘r’ sound like American english does. Besides, I feel difficult to pronounce words like ‘remittance’ ‘Britain’ or ‘party’. The ‘t’ turns to another sound?( and if I thought wrong please tell me.) I hope I can improve my English, express myself fluently. Conversation is the uppermost thing. and watch TV series without subtitles!(haha, it’s not a simple task…still a long way to go.) by the way, I love watching TV series like..‘Being human’ …‘Downton abbey’… ’The IT crowd’ ‘The big bang theory’…etc. ----------------------------------------- I’ve got some questions: 1. Is TV series here correct? or have other name? 2. English punctuation marks is hard….. Thank you for correct me. If you need help in Chinese , feel free to connect me. I’m glad to help! (Traditional Chinese. I can also help with simplified Chinese, but I only type Traditional one… :)
