Worried/Scared

I am allergic to everything. Pain med, nausea med, everything. And now that I'm pregnant the baby isn't even letting me tolerate meds I wasn't allergic to before. Even if I wanted an epidural I don't think it would be safe. If you've had a natural birth I could really use some insight, I'm starting to panic. I'm also freaking out about how I'm going to get through the nnext 6 months with no nausea meds. I've been so sick, and already been to the ER once. Everyone keeps telling me to focus on the baby but them saying that just makes me angry, makes me feel like they don't care about me anymore. Another big reason that doesn't help is because I still don't feel like there's a baby in there. I feel pregnant though. I never thought those would be separate feelings but they are.
