Baby steps YA, baby steps... one step at a time, and don't beat yourself up over all the symptoms and issues associated with PTSD. Pick one thing, work it, work it so hard that you are no longer bothered by it, then move to another symptom or symptom within a symptom... just one at a time, and you will find more just fall into place as time goes by. If you don't work on PTSD, it will work on you, guaranteed... and control you, your life, and everything about you. I see it so often, and I see so many people fall fowl to PTSD, and basically it is just a lack of there ability to WANT to fix themselves. Keep at it, and don't become a statistic YA... you deserve so much more than that.
I understand that your physical appearance is a deep part of your PTSD, but at the end of the day, it is just a physical attribute, and not the actual person you are. Remember what I said to you previously, the body is just transport for our minds. Our minds are what makes each person up, not our bodies. Bodies come into play for physical attraction and things like that, which are a natural part of a relationship, and if your partner is still physically attracted too you just the way you are, then you really should give yourself a little more credit, because you must just be a beautiful person.
Peoples curiousity will always get better of them, and honestly, I am one of those people that will ask someone like yourself, what happened! I guess I would do that because I would rather here it from you, rather than talk behind your back. So I guess the real issue is, are those that ask you the ones to bother about? They want to know, they may care enough to atleast want to know, which is far better than just talking about your physical appearances behind your back.
Just some possible food for thought to help you through a difficult aspect of your own trauma.
