1st trimester: A nightmare from hell!

How is it that something that I have prayed for for so long can make me feel so miserable Every! Day! I envy everyone who has had a simple 1st trimester. Every talks about about how great it is. How smooth it's going and so on but I call bullshit. I haven't made it out of bed in weeks. No one told me how miserable pregnancy can be. I have endured nothing but hospitalizing migraines, violent vomiting, beyond SEVERE constipation/bloating/gas and crippling exhaustion. I hate complaining but I literally find myself crying most days because I can No longer tend to my daily activities or even care for my family. They say it gets better but knowing I still have 4 weeks til there's even a possibility of improvement doesn't make me feel any better. Has anyone else had or is having such a rough 1st trimester. Please help me.
