Acne & my doctor

For the past year and a half my skin has started breaking out (ever since I turned 18) before then I rarely got spots just an odd few occasionally and now I always have a collection of spots on various parts of my face.

Do you think I should go to my GP and ask if there is some sort of treatment as I've tried different skincare routines and nothing seems to make any difference.I also have a few nodules on my chin and I don't know what to do.

Sorry this was super rambly I just don't know what to do having so much acne makes me feel so insecure and disgusting.
