If the arm involvement is a new symptom you may need to call your physician.
What you have explained here sounds like anxiety and panic but I am not a professional so I cannot diagnosis.
I used to wake up every morning for weeks and just start crying but I felt more like it was the depression as I just did not know what to do and than the anxiety piece was there too. I was anxious because I was depressed and depressed because of the anxiety which made me feel worthless.
It took many attempts to find the right drug combo and I still feel like it is not perfect. So I know the feeling of waking up in panic mode. I would not even get out of bed as the tears were instant. Just to get up felt like I was moving a mountain.
I wish you peace and hope you have a good physician and/or therapist.
