I agree that your existing name is really omg i'm so dark. It also sounds like AFI lyrics.
Stay away from anything with a season (autumn, spring...) or a present-tense verb, ie "calling, smashing, chasing, finding, etc." Also steer clear of ALL months and days. October, Saturday, September, it's all been so effing overdone before.
Does that give you any ideas?
