My best advice: group excercise

Find something you like to do that is physical and exercise related, then find a group of others that do it too. Join 'em! We are built to be social. We are built to love. Get involved with a group of people that share your goals and want to see you do well. It doesn't matter if it is a softball team, a crossfit class, or a walking group, gathering to sweat and talk is good medicine!
These people will love and support you, especially through the tough times. Endorphins work!
