Disappointment.

I was invited to guild quite early on, but I left it few days ago. Almost all active members were at max level, so I quess there is no real reason to play together because I'm still at so low level compared to them.

Finding a Free Company that suits you better might help a lot. Some are really focused on just endgame content. Others are about helping FC-mates through the lower level content. A group whose focus isn't on the content you're doing isn't going to be much help. There are forums set up for each of the game's servers. The one for whichever server you're on would be a good place to ask about Free Companies if you want to find one that's more compatible than your last one.
