Hi there,  


I've recently been diagnosed with anxiety by my psychologist after my GP recommended me. The past year, I have been experiencing numerous symptoms that seemingly have no cause. This ranges from stabbing pains all over my body, muscle twitches everywhere, severe headaches and bouts of vertigo, to chronic constipation. I've done numerous tests to figure this out but all have come back fine (MRI, EMG, Blood tests etc).  


I'm quite upset by this diagnosis because it feels like they're just chalking it up to anxiety because they can't find a cause yet. And honestly, it just freaks me out even more that there's something undetected brewing inside me. My wife wants me to visit another doctor to see what they think.  


Before I do that, may I ask for some advice? If these symptoms are really caused by anxiety, can they occur even when you're not feeling anxious? Some days I feel like I'm in a really good headspace but suddenly I'll be hit with a debilitating bout of dizziness that pretty much ruins the whole day for me. The stabbing pains and muscle twitches are also a daily thing for me whether or not I'm feeling anxious. I have also been on Mirtazapine for a couple of months but it's not really helping with any of these symptoms. I'd just like to ask if anyone has experience with similar symptoms and if they can exist independently of anxiety related feelings. Is it still possible that it's really anxiety?  


Any advice would be greatly appreciated.
