Sore Lips

For the past couple of weeks I have had extremely dry and sore lips. I have tried all sorts of lip balms/moisturizers I can find and nothing is helping, in fact the lips are becoming more damaged and sore with time.

Not sure what caused this and it sounds silly I am losing sleep over it because the pain is constant. I would feel silly contacting my GP over something so trivial so if anyone has any ideas of what is causing it / a solution then PLEASE let me know xx
