My huge mistake was studying Japanese to pass the jlpt but I never had the time to speak to anyone so I don't know how where or what to do ( my life is hard so excuse me if I seem an idiot)
So, based on what you say, are you saying you already know Japanese, but you don't have speaking practice? If that's what it is, there are websites that have to do specifically with talking with natives in the language you're trying to learn and then you help them speak with you in the language you're native in, I've never done those myself but I would recommend looking into them if that's what you need.
If you're saying that you need to study Japanese and speak it, well, Renshuu has some of the best (if not the best!) Japanese lessons out there on the Internet, so you're at the right place! However, to my knowledge there isn't actually speaking lessons here (never done one anyway, pretty sure there aren't), but there are words and sentences you can listen to, if that's what you need.
There's plenty of different ways you can practice speaking Japanese; personally I use an app called Hello Talk, most people will want to practice their language with you.
