My left side of lip raises more than the right while I am speaking. Can you advise me on how to fix this?

It's quite normal to have asymmetry in your face and lips. It may be possible to resolve your problem with Botox to relax the muscle that's pulling too hard on one side of your mouth and even up your lips with hyaluronic acid fillers such as Volbella. Consulting with a board-certified dermatologist will let your asymmetry be evaluated and solutions proposed.

Without a photo or seeing you in person, impossible to say. Most of us have some degree of asymmetry. A combination of dermal fillers and Botox can often correct symmetry issues. Schedule a consultation with a board certified plastic surgeon to be examined and discuss your options.
