annoyed... and am I crazy?

Husband just doesn't understand anything that I'm going through. I say I'm sick he has some stupid comment.. I say I'm tired it's like he does things to keep me awake. Im extremely emotional right now and he's a super sarcastic person with everything and I love his sense of humour but I can't take it anymore gets me so upset and it seems like he just doesn't want to learn or I say something one day then it doesn't apply the next day to him.. How do I either help myself or him because I'm not ready to deal with this Childish crap my whole pregnancy 😕😕
