So, long story short: 24 minutes (12 minute per segment).
For whatever reason, today has been a panicky day for me and I had to focus really hard to keep it from turning into a full-blown panic attack. I have been so tired this last week and don't know why. The only time I've felt like I had 'control' was when exercising. I'm sure it's hormone related. I hate hormones. I am at least thankful for getting the relief I do when exercising, even if it is brief on some days.
