Anyone else feeling unhappy during pregnancy?

I'm week 7 but feel like I've already been pregnant for a long time. I feel ungrateful for being unhappy because we had a miscarriage before and getting pregnant again was not easy. But it's difficult to feel grateful when you feel sick all day but can't eat, or when you're bloated like a balloon. What's worse is you are discouraged from sharing your pregnancy with others so early so you need to isolate yourself cos you're sick all the time but nobody should be able to find out. Sigh sorry for the rant but googling "Is pregnancy worth it" wasn't helping so I hoped someone out there might understand. I can't see the joys or benefits of pregnancy at this moment and it's really bringing me down
