anyone else to tired??

I'm almost 32 weeks, and I have like no energy left :( when I get home from work I get a shower and pass out... my husband is deployed and he knows I've been going out a lot to eat, and he's a bit annoyed with it because I'm spending more money by going out then staying in.. I know I shouldn't be spending so much on fast food.. but after working a 5 hour shift and coming home afterwards fast food sounds so much better then having to stand on my feet for another 25 minutes to cook something.. (I'm a cashier) I was going to cook yesterday and even clean but as soon as I got home from my doctors appointment I passed out till 430 then I had to go out again... by the time I got home at 8 I was to exhausted again to cook... this third trimester is kicking my butt... anyone else extremely tired??...
