OK heres the deal, or maybe I don't know how to do that.Everytime I create online custom game after hitting go/start all shit happens besides that chosen map loads immediately and I'm alone.If somebody could give me a hint cause I've checked all options and have no idea what to do...

Huh?

If you create a player match, you'll be dropped right into the game. There won't be a lobby or anything, if thats what you're expecting. The idea is to start a game, and wait for people to join the map. This will depend on how good your connection is and so forth.
