I've lost a few regulars over the years, the last one only recently as she's simply vanished so my commiserations as I know the feeling.
There's always a gap period until you find that next one so sadly you need to wade through all the dogs to find another God.
My go-to remedy for overcoming the loss is to book yourself a nice trip away, somewhere that has pussy on tap and is cheap (SE Asia) and just plow through as much pussy as you can until your dick falls off or you die of a heart attack.
Surprisingly Singapore is cheap as chips with good quality birds so your family and friends don't really bat an eyelash that you're visiting there, even though it's for a sexpedition since SG doesn't have that stigma of say Thailand or Philippines as a sex tourist destination.
In Geylang district, you can basically pay $50 for Thai, $60-70 for Viet, $100 for Chinese for short time (30mins), there's plenty to choose from and you'll be fucking your brains out in between eating delicious and cheap hawker meals.
Best way to get over a bird is to get under another one (or two or three)
