It's seriously too hot, it's making me moody as hell! Anyone could say something wrong to me and I would completely snap or start bawling. Only 25 weeks along and I'm already done. I'm so uncomfortable and tired. I wasn't even this moody, uncomfortable or tired with my first. What's going on?! I just want to sleep for days and not have to get up. 👎🏻👎🏻👎🏻💀 feeling so depressed and just blah lately.
