Judging improvement from tmj treatment.

During my final phase treatment of tmj i.e. braces after splint therapy I have observed something on my tmj problem.... 1)My upper and lower pre-molar and molar teeth are touching slowly when I close my mouth 2)I am now able to chew more comfortably than before 3)my facial appearance is becoming normal But even now the facial muscles related to tmj  are so tight and my upper and lower teeth don't fit with each other and I have some tight muscles in my neck and shoulder area. What those signs indicate? Is my condition improving? Will I be totally normal after the treatment complete? What type of symptoms I would experience if there is something wrong in my tm joint and muscles? Please clear my all the doubts... I am really suffering from frustration, depression, anxiety, nervousness etc. Please help....
