If you really want to do it, start driving, get on the freeway, and start screaming as loud as you can for a while.
If you still feel like you want to jump ship when you're done with that, go home, clandestinely pack your bags, collect all your money including from the bank, and drive off. If you do feel better after that carry on as normal and repeat as needed.
What helps me, personally, is going for a walk. Surrounded by nature, I literally have to force myself to think about my troubles; I go out for walks not to collect my thoughts, but to escape them, and it works like a charm.
Sounds to me though like you're still in the thick of your emotions and you just want to stew in your own juices. So if you like, put
Simon and Garfunkel on repeat, write your incoherent emotional ramblings down on paper (I recommend burning said paper soon after, or burying it if you see fit), and let the pain flow for a while; just be sure to pull out of your tailspin after a couple weeks.
When you've independently reached the conclusion that you won't always feel this way, go outside and do some hard work that makes you sweat buckets, it'll dispel whatever's left of your pains.
That's what's worked for me in past and present.
