Firstly, whilst I agree with some points from Al Ummat I'd just like to say that you're being a little unsympathetic (and to be honest that's not the best way to give dawah, we should do it with kindness).
But about your question, I can totally understand if it's upsetting you (I think we'd all love perfect skin!), and my best advice would be to look at acne treatments (try seeing your GP/doctor, who may be able to prescribe something for it?).
As for the surgery however I've heard that we're not allowed to have it for beauty reasons (only if, say, we're in an accident and need to restore a part of our body, then surgery is ok) BUT, seeing as I cannot provide any verse from the authentic hadith or Quran, please double check this because I may be wrong.
Ps. we all go through difficult times, it's the whole point of this life, because we are being tested by Allah to see if we're worthy of going to Heaven. So the best thing to do is be patient and seek help in Allah, with whatever issues you're going through, and put your trust in Him. After all Allah will always listen to our prayers, and He will do the following things about them. Either answer it so that we get what we want, or save our reward for the hereafter instead. I hope this helps :)
