Sometimes, taking a break is not a bad thing. Look at it this way, taking a break can allow your body to rest and regenerate itself. Also, you may need to change things up, sign up for an event that you normally would not do or join a new group that gives you a different perspective on running. There are ways to get past the rut and be happy running again! You just have to find your cup of tea.
How do I reward myself. . .massages and sleep! I am so busy with my family that after I have accomplished a tough 1/2 marathon or any major running event, I go for the massage, sleep and quiet. LOVE!
