Efficiency of my treatment for tmd.

My dentists started my treatment for tmj disorder more than a year ago.  After successful splint therapy, now my treatment is going on with braces and elastic by an  orthodentist. Now sometimes I feel my bite is becoming normal (because now I can chew food better than before) and sometimes I doubt whether my treatment plan is working or making my condition worse.I have also noticed that my lower row of teeth are moving backward and making my upper front misaligned teeth more visible to people. How can I clear my doubts  and judge whether there is anything wrong in my jaw joint or not by observing myself? Can I do massage on my jaw muscle? Please tell me the restrictions that I should follow during daily activities and massage 💆? Please help me.... I feel lonely now...
