I am SO, SO sorry that you have found yourself on this journey with the results you have. I know how you feel on so many levels. I have replied several times thinking you had a different graft surgery,,,, but I am hopeful that you will have more significant results with a little more time. I know just how hard waiting to see movement is and can only imagine the impact at 24,, I am considerably older. Being retired I haven't had to deal with getting in public if I don't want to either.
I see you are in Spain so not sure how your health system works,, but are you able to get a referral to a psychologist or psychiatrist in order to speak openly to a professional who may be able to help you get a better perspective on your future? There is hope,, always be hopeful,, that your facial tone will improve with a few more months. You may never be able to return to your dream job but I am SURE you will find something else that you can embrace with the same enjoyment once you heal more.
Please try to find a professional to speak with and maybe get a prescription for some anti depressants to make it through this admittedly very hard time. It is very hard for others to relate to the loss we feel when our looks have been taken from us so quickly. It DOES change how we feel about ourselves and how others relate to us. We "see" it EVERY day. But you have to dig deep inside and find yourself,, you are still there,,, and there is life, a good, full life ahead.
After some more healing if you don't get the results you hope for, maybe you can look into another surgery to increase your ability to smile. There is one in particular, the gracilis free flap, that I have been told about to increase muscle movement and tone in the cheek area. Not sure they preform it over there, but you could check. But as I say,, I think in another 6 months, you will see even more healing yet. Please hang in there and know you are still the beautiful person you were before your surgery!
My thoughts and prayers go out to you sweetie! Surround yourself with those who love you and are positive and realize you are still beautiful,, Jane
