I literally don’t know what else to do

I got my OCD diagnosis about two years ago, in the beginning is was a constant rechecking of things, locking doors pulled the handles and knobs to make sure they are REALLY locked, light switches, going back in the bathroom 6 times to make sure I unplugged my hair straightener. Then over time it developed into this nasty soul sucking monster that I feel like literally consumes me everyday.

For the longest time I had a fear of touching trash or picking things up off the ground out of the fear of it being laced with drugs, I can’t eat food made by other people unless it’s me or a close family member due to the fact I think it’s laced with drugs.

Over the last 6 - 8 months I have started experiencing I guess health ocd? I have convinced myself I have brain cancer, female pattern baldness, diabetes, liver failure, kidney disease and I mean the list just goes on and on.

I have tried CBT and nothing is helping me, I feel like I’m rotting from the inside out, I literally don’t know what to do anymore.
