This is a very common problem known as a left AIC pattern. Essentially, due to overuse of a chain of muscles across your left trunk, pelvis, and femur, the left half of your pelvis is anteriorly tipped, causing your entire pelvis to abduct and rotate to right. So as of now, your pelvis is "twisted" in three planes of motion, leaving your left femur abducted and exteriorly rotated and your right femur adducted and interiorly rotated. You need to realize that currently, it is IMPOSSIBLE for you to create symmetrical movement through your trunk and lower extremities because the 3 bones and 6 joints of your pelvis are not in their proper positions.
While treatment can be a fairly involved process, progress can happen quickly and you should notice (at least) acute improvements after a single session of treatment. Find a Postural Restoration Institute (PRI) certified physical therapist, as they will be able to quickly identify and begin treating the issue. It is unlikely that someone without PRI training and certification will be able to help you, and even less so that you will be able to work this out on your own.
