It exposed real life problems, it dealt with suicide more than once, yet i didn't find it depressing like Kimi ga nozomu eien, or Ef: a tale of memories. I'm not experienced in this field, so i don't really know what it is that made me enjoy this series so much, but i really loved it.

Maybe because Welcome to the NHK is a black comedy romance (like I said before). I think the following will help you understand more about black comedy. Here’s a description of black/dark comedy from Wiki:

Spoiler for Black/Dark Comedy description:

The terms black comedy or dark comedy have been later derived as alternatives to Breton's term. In black humor, topics and events that are usually regarded as taboo, specifically those related to death, are treated in an unusually humorous or satirical manner while retaining their seriousness; the intent of black comedy, therefore, is often for the audience to experience both laughter and discomfort, sometimes simultaneously.

EDIT: Welcome to the NHK began as a novel then adapted into manga then later into anime. Each adaptation is quite different from each other in terms of themes and characterization. So, you can't exactly found the continuation of the anime in the other media. Still, the novel and the manga are worth a shot.
