first diagnosis

I have been sent to a rheumatologist who is reporting suspected polymyositis.  He has referred me to a neurologist but I will not see him til march 20.  i am on a cancellation list.  7 months ago i noticed weight loss followed by a difficult with walking and a lot of pain in left hip sometimes causing sciatic nerve pain in left leg.   Thanksgiving i found i was unable to lift or carry anything, even someting very light weight.  The hips seemed to push forward and the shoulders would droop down.  I currently weigh in at 106/107 lbs.  Sometimes the pain is unbearable and I sit and cry.  I am a natural health nut and have always exercised, yoga, lifting weights, taking supplements etc.  My family doctor did not take my aches and pains very seriously, although she was very disturbed about the weight loss and lectured me on eating more.  I eat well and I eat healthy.
I do not quite know what to expect for my future life, it sounds as though nothing is going to be quite the same.  I so miss my mobility.  I am currently trying to use a walking stick.  The rheumatologist tells me i will probably go onto steroids, but i have to see the neurologist first.  So i am playing a waiting game which is very frustrating.
This group seemed to be a very caring group and already i have learned a lot from reading your posts.  I have a lot more to learn, this is all so new to me.  I guess the neurologist is the one who will do the muscle test, then i will know for sure.  
Very anxious and a little scared at this point.
