Suicidal but not depressed?

[Aries]

To start things off, I am not in a depression, however I've come to this state of mind where life seems to have no appeal to me anymore. I mean, things right now do kinda suck, I can't get a job to save my life, my mom is struggling like hell and I do my best to help in anyway, after high school I pretty much lost contact with my many friends (only contact is through Twitter & FB every other day lol), and well, not to sound overconfident, but I already know what's in store for me in the future. I know it really sounds stupid but I know what I'm going to do and what I will do to get to my goals, AND I know I'll accomplish them. I always have. But now I kinda just have more curiosity for death than life. Life, to me has no absolute appeal anymore. Is this normal? Should I go to someone? Am I going mental lol? Again, I really am not depressed. I'm still a happy person Besides, I don't believe in depression. (Another subject.)
