to cry over being tired?

[CherryAide]

I'm 32 weeks pregnant. Woke up this morning as I need to go to work. Getting gradually more exhausted and just getting out of bed is awful because I sleep so badly. I've cried a few times this week just because I'm so tired and can't function properly but I have to go to work. Not sure if crying because I'm emotional, or drained, or need more sleep. I'm not usually a crier.

Has anyone else found that exhaustion/pregnancy has had this effect? I feel a bit pathetic and trying to hide my exhaustion at work makes it even worse...

I remember when I was 30 weeks exactly and feeling absolutely shattered. I could even bend my knees. A relative kept telling me to be tough and that when she was full term she was still running around and doing every thing. That night, I ended up a+e and had a emergency section at 31 weeks. For me the reason I was feeling so bad was because of an infection.
