assuming you're actually from albania, you should start at the lowest div in ETF2L (Open i think it's called)
if you're from na you should play one season of UGC Iron and after finishing that season you should look for a ESEA open team

(sorry if im wrong or sounding like a smartass) but isnt esea open for more advanced players? like iron to open seems like a huge step.. and yea im from na i forgot to change it back to usa

ESEA Open is, guess what, open.
Anybody is welcome to play in ESEA, although keep in mind you have to pay fees to play and its a bigger commitment than UGC (you'll normally scrim at least 3 times per week, depends on the team).

Sure, lobbies will give you bad habits if you spend too long trying to learn stuff there, but for the basics, they're a great place to start. I kind of had to grin and bear some of the personalities there and just resign myself to getting flack while I was new, but it was still a good way to be pretty well prepared to jump straight into steel.

One alternative to tf2c is na.mix.champ.gg. As soon as 12 people add up and ready, it auto-picks teams it thinks will be balanced, based off hidden elo.

There's also Newbie Mixes, a group where newer players get together to play 6s, guided by more experienced players as coaches. That's a very good place to nail down some of the fundamentals in a somewhat less competitive, more learning-oriented environment than lobbies. Mixes happen every Friday. http://steamcommunity.com/groups/na6v6newbiemix

One key thing with these places is it's not just about learning the game individually. If you can find people you do well with and like who are close to your level, that can be the start of a team right there. Good luck with everything! :)

oh, aight thanks ill try to do my best to do what you said

This is true, but not everyone agrees it's always a good plan to jump into open asap. Mid-open was roughly at the skill level of playoffs silver last time I checked. The most important thing is that you find a team you work well with that will live long enough for you to develop with them. Before you're at a level where you can be competitive in open, I think you can still find that in UGC, so no need to rush the transition, especially if cost is a concern.

Don't bother with lobbies, practice your dm, watch povs of prem/invite players, try to merc for other teams and if you get your own team start scrimming a few times a week. Or make your own team and call the shots.

If you've never actually been formally taught how to play proper competitive 6's, join the na 6v6 newbie mix steam group. They have them every friday at around 9 est. But lets assume you hve been taught these basics, I would try a pug group. If you tell them before the game starts that you're not too good, usually ppl won't get too worked up about you doing bad.

On top of that, the group runs a Open team drive at the start of each ESEA season.
Also Newbie Mix PUGs 2.0 group is a decent start: http://steamcommunity.com/groups/newbie6v6pug
