That sounds like a really good approach- the boy's and the dog's legs will be nice and strong, that's a bonus. How do you football train (just curious, feel free not to answer)- when I go swimming I walk past 5 a side pitches, they're usually really busy. Swimming is obviously solitary, I want to do some more sociable exercise.
I don't know much about meds sorry, but I hope it starts to feel helpful. I don't think I've got a chemical imbalance, think I've got a personality imbalance or just difficult circumstances and history. On the plus side, tonight I'm exhausted with back ache and raw hands cos I'm redecorating my daughters room, she really pleased, so I am.
If you're doing the right thing by your son, and you want to reconcile with your wife, I think there's good hope there.
