I've been through three major break-ups. You can can play with the palliatives like drink, drugs, work, gym, tracktime, new and expensive hobbies and especially mindless and meaningless sexual encounters
but the only thing I found that puts the head back together properly is a new and meaningful relationship. If you want to find it the worst thing you can do is to go looking for it.
So I suggest tune up the Porsche and blow the doors off a few inferior makes (on the track of course
) start collecting custom switchblades, improve your gun control and start having fun again with the female of the species.
