Um... those ones that are not finished but have a great story with awesome characters. Honestly, I think Yuuutsu no Asa, which is my favorite manga of all time, is quite depressing. It has so many betrayal and is way too real, that anybody having an issue with trying to find themselves would understand. I hope it makes sense. Anyway, try to cheer up! If you need to talk, drop me an email or message. (づ ̄ ³ ̄)づ
