I feel like I am a little short of breath which is making me very tired. Like... I am ready to go to bed at 7:00 every night. It's like that exhaustion you get your first trimester when your pregnant. No, I am not pregnant. But it's like that and I'm wondering if it's because I am more short of breath than usual. Remember I'm not sick, I just feel a little weight on my chest. It's weird how these subtle symptoms creep up on me. Anyone else???
