I am NOT a doc, so this is just my thoughts: As others have said, it could be too tight of a wetsuit or jacket BC, this is why I changed to a drysuit and BP and wings. It could be quick shallow breathing, rather than slow deep breaths. Again it could be your not in good physical condition. One other thing it could be, if you think you are in fairly good condition, but have the same problem, maybe started recently, when doing other normal activities on the surface, like walking up stairs is hard now, could be a sign of clogged artries restricting the blood flow. A very active friend suddenly found his breathing became labored when doing sporting activities he'd done for years, and ended up needing a stint put in.
