Stress is killing me and I don't know how to fix it

I'm working full time, coaching my son's baseball team, trying to help with homework, wife's got her own job stress, house needs repairs, car needs service. I feel like I'm barely keeping my head above water. I snap at the kids for no reason. I haven't slept well in months. I've talked to my doctor and she suggested therapy but honestly when would I even go. Does anyone actually have this figured out or are we all just barely surviving out here?
