I chose Envy and Pride. Envy because I've always resented the fact that other people seem to feel things that I think I've never felt completely (being in love, being loved unconditionally, self-confidence). And I chose Pride because of course I'm never going to admit that to them.
On a sidenote, have you noticed that envy is the only sin you can't be proud of? Lust is admired, gluttony is often seen as funny, greed is a virtue for many and so on. But envy is always malignant and despicable.
I'm with @Out0fAmmo - there aren't seven deadly sins. The closest we have are the seven things that the Lord hates, and those are different than the seven sins typically associated with the term, "seven deadly sins."
I am not defined by sin, but by a relationship with Christ. Therefore, I am not a sinner who struggles to love God, but a lover of God who struggles with sin. Romans 7 vs. Romans 8
