Most of all, Lana's the type of person who always strives to be honest with people and takes it very seriously. She can be a hypocrite at times, being careful about how she and Clark break their relationship to Chloe for example, but overall she takes honesty very seriously and considers it the most important virtue a person can have. It puts incredible strain on her relationship with Clark that he's never honest with her and that he constantly hides things without bothering to give even the slightest explanation. Her pursuit of the truth isn't nearly as prying as Chloe's, but in a lot of ways when she gets very intense about finding it, she'll do what it takes to follow through her agenda. Her want of the truth and her goal-driven, strong will combined can make her a dangerous operator in a lot of ways. She'll go to some dangerous lengths to pursue what she perceives as justice and get to the bottom of things.
In Truth, Lana confesses to Chloe that she just wants to get out of Smallville, even though it's her home, to get away from all of the people that she perceives are judging her. Her self-awareness translates to a worry that people are judging her, that they consider her too driven and self-involved. She confesses that she doesn't trust Chloe, her closest friend, and it makes it clear that she doesn't really let anyone close enough to trust them with that inner Lana. With her hopes and her dreams and her insecurities. She's aware of her flaws and lets her insecurity about them separate her from people.
Despite how driven and self-involved she is, Lana doesn't trust herself because she frequently makes wrong decisions, then when she realizes it's wrong, can't get herself out of the situations she's created for herself. This also means that she'll follow her bad decisions out to the end of the road before admitting she was wrong or before trying to rectify things. It's her way of taking accountability for her choices. That is part of why she sticks with Lex for so long despite obvious evidence that he's not necessarily trustworthy. Essentially, she gets to a point where she tries to hold herself back from doing things because she never trusts herself to know whether or not it's the right decision, and the consequences frighten her. It often leaves her stuck in a limbo where she's afraid to make a change in her life, but usually there is something to shove her into breaking the final straw and making a huge change.
Her relationship with Clark gets pushed to the point of breaking just prior to her hooking up with Lex and it changes Lana in a lot of ways. Lex, as she professes as early as season 2, has an effect on her that's both liberating and terrifying. He begins to take the seed of darkness that's in Lana and helps it grow. With his influence, she grows into a woman that is his equal -- both in skill and ruthlessness. She becomes, around season 6, totally willing to keep whatever secrets she decides are necessary to keep the people she cares about safe -- often times, safe from themselves. Not only that but it's when she begins to show that she's willing to go to dangerous lengths to protect them. She demonstrates herself as willing to kill Lex to protect Clark and the rest of the world from Zod, and she later demonstrates herself as willing to kill Lex in sheer revenge because he's "dangerous" and will never stop hurting people.
