My advise is to have a fresh look at your life and get out there and do everything you want to do. Give everything your best shot and something good will come from it all whether you're on your own or with someone.
I have a friend who's Mrs recently left him, he's hit the bottle big time and is going nowhere. Don't take the easy route of getting bevvied up to take the pain away. Face the future and the good times will surely be back
