Second, technology is technology. Yes, it would be nicer to have newer languages on your resume, but any language is a language and having old languages on your resume is better than none.
Third, if you give up after only 6 months, it'll look really, really bad on your resume.
And finally, I have a feeling English isn't your first language. You made quite a few grammar mistakes. This wouldn't be such a problem if the rest of your text didn't seem English-native. It makes you sound uneducated, when the opposite is probably true. If you intend to work in an English-speaking company, or heavily interact with English speaking techs on the internet, brush up on your English.
As for the advice...
Keep your job. Use your free time to learn 'newer' languages. Contribute to open source projects, or start a project of your own. (Contributing is significantly easier because it has built-in direction: Just look at the bugs list and start fixing them.)
Don't rely on other people to teach you. This is a really bad lesson that school teaches and it makes improving your skills a lot harder. That's not to say you can't learn from others, just that you shouldn't be relying on it. Teach yourself and take advantage of mentors as you find them.
