Constant churning

The thing about anxiety is it sucks the joy out of everything - I thought depression was bad! I've got this constant churning in my stomach and my mind and body is on red alert, waiting for something bad to happen. This isn't me. I keep telling myself that there's no need to be anxious. Everything is going ok. I am safe. But still the dread and fear persists.

And the fight or flight mode is not good for managing fibromyalgia either. It's like a double whammy of crapness. I'm getting desperate now, something needs to change. I've requested to up my dose of Sertraline, although I'm worried it's this that's giving me the anxiety. Hamster on a wheel anyone?
