I just found out i was pregnant.

I'm a FTM, 24 years old and scared shitless. My first doctors appointment is next week but my mom says i'm about 8 weeks along. I have a great support group and my fiance is beyond thrilled. We've been together since we were 12... so we've been talking about this moment for a long time. But the process of being pregnant is so hard on me. The morning sickness is so rough that i can't even go to work some days... i'm trying to stay positive... but when i can't eat it's really hard not to feel guilty i'm hurting the baby in one way or another. I don't know... it just seems like an overwhelming amount of things could go wrong. Does anyone have tips to help me survive this first trimester? I hear it gets better... but i'm worried about my job, my health and my sanity, currently.
