You don't know what to live for? Really, over an anime? Man up!
Anime recommendations? Gintama is my favorite and it's hilarious, if you want to see something similar to SnK check out Gantz and Claymore. Sword Art Online is pretty bad. It has a really nice start but it blows it after a few episodes.
The sales for the manga and the anime is unbelievably high, the problem is it needs more material. You see, anime is usually adapted from manga (Japanese comics) so the mangaka (manga creator) needs to draw more. The next season is probably coming out spring season. The anime is really popular so almost everyone in this section has watched it. If you search Attack on Titan or Shingeki no Kyojin you'll see quite a few threads about it.
