I'm begging for help please. I just moved and I don't have a new therapist or doctor yet to help me. I'm diagnosed OCD &amp; andiety; I'm on an SSRI too.

All day every day I'm plagued by intrusive thoughts of my partner dying. He walks to the grocery store and he will get randomly shot. He drives to the post office and he'll get t-boned. He's working at home and drops dead. He goes to sleep and never wakes up. His headache is brain cancer. He eats chips and he's gonna have a heart attack (he's not even fat he's normal). 

How do people go through life and not constantly worry every minute of every day how things can be ruined. I love him so much and we're amazing but all I get are these intrusive thoughts on repeat and I don't even have a compulsion to ease the anxiety for even a minute.

TLDR: How do I manage/cope with constant distressing intrusive thoughts of my partner dying?
