You have 6 pack abs and yet appear to have a moderate case of gyne, with the right side appearing larger than the left.
If you have had this from puberty, it probably will not disappear on its own.
Would strongly advise you to consult with an experienced gyne surgeon if you are indeed contemplating surgery. If no-one is available to you through NHS, then it might be the better part of valor to wear a snug compression garment (to shape your chest) while you save money so that you can engage a private surgeon.
Good luck!
