I don't know what's going on, but lately, I've been really pissed after I exercise. I've only been exercising for 2 weeks now at the gym. I look forward to going and enjoy being there. I spend 60 minutes doing the treadmill, bike, nu-step, and weights. Last week I went 3 times and this week, I've been 5. Does anyone know what might be going on? I mean, I'm really angry about 1/2 to an hour after I get home. Any little mistake I make, I feel like I want to punish myself. Strange. I would've thought that exercising would make me feel better, release those endorphines. I don't know.
