feeling disconnected

I am 8 weeks pregnant and have for the last 3 weeks felt very disconnected from everything. I don't know if it's the hormones or what but I just don't feel like myself. I'm a first time mom so all of this is new to me. My boyfriend (father of my child) is being being absolutely amazing, and I know he just wants to make me feel comforted but I can't stand anything right now. I hate being touched, it makes me feel absolutely suffocated, I assume because I have another life growing in me, draining my energy, making me sick and making everything out of whack. I feel so crazy, depressed and unlike myself. Has anyone else experienced this? If so, any ideas on how to get out this funk? I just want to feel happy and excited.
