So happy to finally be preggo but..

I'm so miserable. I feel so alone, and have so many hormones that I've never had before. I don't know how to handle anything. I am so excited that I finally conceived and I think I pumped myself up thinking it was going to be such a happy and wonderful experience, but so far it's been the opposite. Is this normal? I'm 7weeks 4 days. Will these feelings go away? I feel like I'm slipping into a depression of some kind.
