Just that really. I initiated the break up, it's probably for the best, but I'm just struggling so much. I can't eat, I feel shaky and sick and I feel like I'm losing my mind. Been smoking lots and boozing, which doesn't help, and I know in theory what DOES work: being active, running, music, no contact. But I just feel desperate.
What else can I do so I don't feel so shit? What worked for you?
