I'm there with you...
Clannad is a nice anime using a contrast of comedy and tragedy, After Story goes more into the Tragedy aspect but overall it's a very emotional anime.
Alternatively I would suggest an Anime called Shakugan no Shana, which I am about to rewatch soon
Some more that I really liked are: Elfenlied, Deadman Wonderland, Dog Days, Seto no Hanayome, ChaoS;Head and various others. I bet if Churro sees this he's going to be like "Watch K-On, it's a great anime!"
But really just look into some anime, check out what kind of style you like and start from there, if you don't like something, don't watch it and maybe look for a different anime that looks more appealing to you.
