Just wondering, is it normal for your arms and legs to feel very heavy when you are depressed? I'm pretty sure I have depression and low mood of some kind which is always there, but during very low points, some times it is hard to move my limbs or even walk, I have to sit down where I am standing and wait. And my breathing feels very slow. This feeling only happens during when I am really depressed, so I don't think it's a symptom of another sickness, but should I see a doctor about it in case it is?. I'm not currently on any meds.
