I'm so sorry you had such a struggle today. I understand how overwhelming it is to be the only parent. I know you have to know this, but you are the BEST parent your kids could ever have. How do I know this? Because you worry about how your actions are affecting them. A parent who is just going through the motions barely thinks about that (trust me - I know. My xh has next to no interaction with our son except the 4 days a month he "plays" dad).
Keep your chin up sweetie and don't stop the running. You need that. Could you get the kids involved in your running somehow? Even in a very small way? Maybe it could spark an interest for them.
