If you can't, that wouldn't be much fun, would it? But the term "short term pain for long term gain" applies here. What I mean by that is you should not just jump from meet to meet, striving for your PR at each meet, and the heck with kicking yourself of the habit of being under. Depending on when your major meets are, and how quickly you're progresssing towards improving your technique, you may need to sacrifice some early (e.g. early indoor) meets - not necessarily any indoor championship meets. But the pace at which you improve is directly affected by the coaching feedback you get, and how quickly you're able to learn from that feedback. That's why I urge you to find a coach that can work with you every day.
I've seen so many vaulters get into the vicious cycle of training meet-to-meet, thinking that they cannot afford the time to fix their habit of being "in" (and of course wanting to do well at each meet), and inevitably just getting hurt again. Once you're hurt, then you may have to skip some meets anyway, so the logic isn't there to just strive for the short term gains and to heck with safety or good technique.
Set a target for what meet is most important to you, and work towards doing well in that meet. All other meets prior to that one, don't set a target of how HIGH you want to jump. Instead, set a target for improving your technique. This may be an oversimplification, but for example, set a target for getting your takeoff point back a certain measurable amount each week. If you do this, you may be surprised how your technique just "automagically" improves, and your PRs also improve.

I've heard suggestions that i should move my run back because then i will have room to pick them up. Just wanted to know what you guys think.
I'll let CoachEric and Altius answer these particulars. CoachEric has already addressed this a bit, but I suspect your problem is more of just that your body has become accustomed to being "under", and no matter what you do (what your brain tells your body to do), you body is still going to override your brain and get to that "under" position that it likes.
This is why I think it's more psychological than physical. CoachEric and Altius have laid out some good drills to break yourself of this bad habit, but I think it's important to understand that bad habits are hard to break, and it's not as simple as just correcting a minor flaw, such as not lifting knees on last 2 strides, or the mechanical actions of your pole plant.
With all due respect to CoachEric, I think Altius' suggestion to work on getting your stiff pole grip as high as possible is the BASIC drill to work on, and maybe CoachEric's drills should come after you've become accustomed to an "out" takeoff.
