Hello Maraki!
My 2cm by 1.8 cm AN was removed on Dec. 7th, and was sitting directly on the facial nerve. In fact, they left 1mm of the tumor in to avoid facial paralysis. But I knew it was possible, and I deeply understand the depression that it can cause - I went through that depression BEFORE my surgery, worrying about it. It is completely natural that you should be struggling with your feelings right now. You are dealing with a lot.
Also, I have a dear friend (and his family) in Athens who has Myatonic Dystrophy, and I visit regularly. One of the things I have always noticed is that Greece (forgive me for saying it) is not very 'current' in dealing with any form of physical difference. I remember that I had been visiting Athens for 15 years before I saw my first wheel chair in public! I know that your situation is not that 'noticeable', but I think that part of your fear(?) is that the general public is not very aware of physical differences caused by illness/etc.? That is just my idea, but I know that it's part of the difficulty for my friend. He can no longer walk, and he looks VERY ill (wasted muscles), and he always has some reservations when he has to go in public.
From your post, it sounds as though you are looking pretty good, though, and will look better in time? One thing I can give you as a piece of advice I was given years ago "There aren't nearly as many people looking at you as you feel there are, so don't worry." And I have found that to be true. Most of the time, when I get self-conscious, I realize that nobody is noticing me but me!!
As for findinging someone - you will. Work on who you are inside, and ask God to send you the right person, and He will. Love has to be something that doesn't matter what happens to our faces, because age happens to all of us, and beauty is fleeting. Take care, and hang in there - the depression really does get better.
