Blepharoplasty gone wrong, 3 weeks post-op. Advice? (photos)

I think it says a little about your personality, that you are complaining about your upper lid blepharoplasty result ('blepharoplasty gone wrong') when you are looking at the early postoperative healing, not the final result.
I agree with the observation of Dr Andrew Campbell, that the photos show what is giving every indication of being  a very good result.
It is a pity for you that you are going through this phase of doubt and anguish, unnecessarily.
Better for you that you seek reassurance from the surgeon who performed your surgery than from social media. He, or she will be able to expoanin what was done at the time of surgery.
Also the essential aftercare, especially about keeping your head elevated to minimise swelling, which I suspect has not been the case. It would be good for all to see your result at 4 months and then the very final outcome at a year, end then how you fee about the result then.
