Rapid Weight Loss And Change In Taste And Breath Odor

I'm not quite sure what to think anymore since my family thinks i'm doing something to make me lose weight. I went from 134 lbs. To 102 lbs. In a matter of 3 months without changing any eating, drinking, or exercising routines. My husband says that my mouth "odor" is different ( not saying I have really bad breath), but that it's changed. I'm almost 35 and have never had any dental hygiene problems( not even a cavity). My physician ran some tests including a tsh & comprehensive metabolic panel, but results were normal. Tsh=0.53 and glucose=79.All blood levels were normal.
What is really bothering me is that I read on the website about hypothyroid problems and I do have most of the symptoms. I feel tired all the time, take medication for anxiety and depression, and I have a pain in my left shoulder socket and my right hip socket. What should I do about talking to my Dr.About running more tests? Should what she's done be enough to say everything's okay with me? I am now wondering if i'm alright (like my family) because i'm not gaining weight , but I eat more than I did before. Does anyone have any answers for me? I really appreciate it. Thank you.
