Yeah, Garrett, you're all alone. JUST KIDDING. I can pretty much guarantee that we've all felt like that---that is, if we care about our relationship with Yahweh (a baseline indicator that the Ruach Qodesh is convicting us of our sins, in turn proving that She is dwelling within us). Your discomfort with your shortcomings is actually a very good thing; if you felt perfectly comfortable sinning, then you'd have a problem.
Check out this passage: "He who believes in the Son of God has the witness in himself; he who does not believe God has made Him [i.e., called Him] a liar, because he has not believed the testimony that God has given of His Son. And this is the testimony: that God has given us eternal life, and this life is in His Son. He who has the Son has life; he who does not have the Son of God does not have life. These things I have written to you who believe in [trust in] the name of the Son of God, that you may know that you have eternal life, and that you may continue to believe in the name of the Son of God." (I John 5:10-13) So it is possible to know you are "one of His." Know it, not just wish it to be true. The criteria? "Having" the Son of God by believing---trusting, relying upon---His name. And what is that name? Yahshua: "Yahweh is salvation." The criteria is not "having attained a sinless state in your own strength."
Fair enough, you say, but what about verse 18? "We know that whoever is born of God does not sin." Ooooh, ouch. Does this mean that if (actually, when) we sin, we demonstrate that we are not "born of God"? No, because none of us reaches behavioral perfection on the day of His salvation. What happens when we inaugurate our walk with Yahweh, rather, is that we are given a "garment of light," called metaphorically clean, white linen---the righteous acts of the saints. This garment conceals our sin from Yahweh's eyes, and if He doesn't "see" it, it doesn't exist. So in a very real sense, "Whoever is born of God does not sin." He may do things unworthy of his salvation and his God, but those things don't damn him any more than a three year old who steals a cookie loses his identity as a family member.
However, those sins, though no longer damning, do us no good at all. God has been known to spank His children, or more often, refuse to rescue us from our folly, letting us reap what we'd sowed. That's why Paul exhorts us, "Do not quench the Spirit," and "Do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption." And how do we do that? Well, how do you grieve your mother? By refusing to heed her advice, by putting yourself at risk, by running with the wrong crowd, by doing things that aren't good for you, by being part of the problem instead of part of the solution, by beating up on your brothers and sisters. You get the picture. God hates our sins because they're bad for us. They don't do Him any harm at all. But when we sin, we done the spiritual equivalent of an angry teenager going to his room and slamming the door---cutting off communication. Because He loves us, Yahweh would spare us that pain.
