Feeling miserable

I see all of these women say that they are feeling good . I am 25 weeks and feeling absolutely miserable . I feel like I can't breathe , my back hurts , my feet hurt, my shoulders hurt , the top of my stomach hurts , I'm exhausted , I'm hot all the time , I feel like a whale , I can't get comfortable , I have to roll out of bed and I don't ever feel like getting dressed .
