29 weeks tomorrow and I feel like I've been hit by a ton of bricks. I don't want to do anything, all I want to do is rest. I have to fight with myself to accomplish even the tiniest things because it takes so much energy that I don't have. It's making me feel pretty bummed out. I can't figure out if I'm feeling low because I am so tired, or I'm feeling tired because I'm feeling so low. Anybody else experiencing more extreme exhaustion right now? I just wish I knew if it was low iron or not enough sleep or baby growing or if I'm just getting down in the dumps. Physiological or psychological? Or Both?!!!'s like I need my batteries recharged! I was doing so well in the second trimester!!!!
