I've battled anxiety for years, have been prescribed Effexor and have been on and off.

Recently, without warning, I find I'm catastrophizing over everything and I can't relax. I'll pick something mundane and unlikely but remotely possible (like having my wallet stolen at the gym or having my phone charger overheat and catch fire) and I am completely unable to let go of the thought.

I've got like 10 things I'm losing sleep and sanity over even though I know they're unlikely and not even huge deals if they happen, but I've been unable to move past them.

My doctor put me back on Effexor (as of a week ago) but I need some way to get through in the mean time. I can't relax, I'm having trouble leaving the house, and I'm driving my wife and friends nuts.

I've always been a worrier and always prepare for the worst but I've never been debilitated by thoughts of catastrophe before. 

Thank you for any advice or comfort
