So desperate for end of first trimester

I hate to say this, but the first trimester has been the worst. I know pregnancy is supposed to be rainbows and sunshine and everyone is so glad to be pregnant, but I'm not...I want this baby so badly, I want my own little family but I'm completely miserable..

And I feel so horrible for saying these things, but I'm constantly sick, I hate working at my job since I got pregnant and nobody will hire me because they don't want to give me benefits, I can't sleep more than 3 or 4 hours a night before I wake up and lay awake until my alarm goes off.

I had my first ultrasound on January 3rd and I thought I was 9 weeks when I went in, they put me at 6 and 3 and didn't tell me what the heart rate was. As I have PCOS and it took so long to get pregnant I'm confused and concerned.

I'm starting to get worried that because I'm having such a tough time with this first trimester that I'm going to end up a bad mom and I don't want that at all...

Do you ladies know what this is like? Or am I just being stupid?
