I can relate. Slowing down the past several weeks, and going no aerobic completely for 11 days, was killing me mentally. Except now, I get to get back into the daily swing--and hopefully soon, twice a day-- b/c ds is in school and the weather is cooling.
I still think that since you are spending time on campus, you should check out the workout facilities at your college. No weather to worry about and you could clean up right in the locker room for your next class (or work, whatever). Or you could run/walk around campus, but use the facilites to clean up. Just a thought to help keep up your frequency
Even running 3 days a week is better than nothing. I hope you find a way to fit it in! Best wishes!!!
