Sorry for the stress you're dealing with.
Hope things start looking up soon.
On those days when I just don't feel like working out, but know that a workout will make me feel better, then I do whatever I feel like doing and don't allow any guilt over it. I'm almost always thankful that I pushed myself to do SOMETHING.....anything. So, grab whatever workout you feel like you can do, and do it. For me, I gravitate toward my easier workouts but still get a decent sweat, like:
My Personal Best Workout - LOVE the overall scenery!
Step Reebok - the Video or AeroStep - requires very little brain power.
Cathe - LIS or HIS from the 4DS series b/c I love the footwork and it flies by.
Cathe - Lean legs & Abs - fun workout with good music.
Les Mills Pump - any of those disks b/c the music rocks.
Cathe - To the Mat - if I just don't even feel like standing to get a good w/o.
If I need something inspirataional but tough, I'll opt for Sean and do a Cardio Coach on the elliptical or a Katami 4x4 w/o with Paul. But I typically just want to do something a little more layed back when I'm not feeling up to working out. Sometimes I'll just stare at my collection and pick one I haven't done in a really long time just b/c I can.
