Totally normal to feel this way - I was throwing up 5 to 15 times a day from 7 weeks to 13 weeks and was on anti-emetics in weeks 11 and 12. Ended up having 6 weeks off work although thankfully avoided hospital.
It was the grimmest time ever, but rest assured it does get better - I'm 20 weeks now (2nd scan on Monday) and looking back now, that 6 week period seems rather like a nightmare seems when you remember it at 4pm the next day, out in the sunshine and warm breeze! But I know how hard it is to believe there will be any end to it when you're in the thick of it with your first experience of the first trimester.
It's awful awful awful at the time - not only the sickness but because your hormones make you feel so down and blue you don't want to do anything or see anyone. I remember I thought to myself "frankly if I have a miscarriage I really won't care - anything to get rid of this awful feeling!"
But rest assured it does get better, and you're nearly there. Everyone is different, but I'm pretty sure you'll find your mood lifting and the sickness reducing from about 12 weeks onwards- and many people say that by about 15 weeks they're feeling positive and normal again.
You're right about the depressed mood in the first trimester - but this does change as your hormones settle and the placenta starts working fully. I have found in the 2nd trimester I've still been tired, achy, hungry, exhausted (certainly not "blooming!")but somehow your hormones are different and although you have these discomforts you don't mind so much and your basic mood is good - epecially when you start feeling kicks and really thinking of your baby as a little person! Although I'm zonked after work and achey all over, I'm excited and happy at the mo and thrilled to be pregnant.
Plus - sickness is good - means its all happening vigorously in there and is usually a sign of a robust baby, don't they say?
Hang in there - in a month you'll be looking back at this time feeling v relieved its over!
