Feeling Defeated @ 11 weeks

I am at 11w5d and I am having one of those moments where I feel totally defeated by the little one inside of me. I am a newlywed who’s been trying to conceive since June. I am also an elementary school music teacher (concert season is in full swing!) and feel some stress about that but my lack of energy every day has me even more stressed! I wake up and immediately throw up every morning and go throughout my whole day dancing and singing with the kids on the verge of throwing up. Came in to work today and cried throughout my whole prep period!

Is anyone else feeling or have felt like this? Hubby is amazing and sympathetic but think I just need some moral support!
