Worry anxiety weakness could be Addison disease?

[Kkmom]

I suffer from GAD and under lot of stress. I’ve had every symptom you can think of but the newest I’ve not had is feeling like I’ve been dead lifting weights. My arms feel shaky weak and little in legs. Could this still just be anxiety related? I’ve had for few months it will get a little better and then worse again especially triggered my high stress situation. Anyone else relate? I stumbled upon Addison disease and now so worried it’s that

Shakiness and weakness is very common with anxiety. I've experienced it quite a bit when dealing with anxiety.
