feeling sad

8 weeks pregnant and so thankful to be pregnant so I feel bad for admitting this but need to get it off my chest. My morning sickness and fatigue is causing me to feel sad and a little depressed. It's like I see everyone else feeling great and doing everything and keeping up in life and I just feel lonely on the couch. My husband and children are so loving but they have sports stuff to keep up with and have been busy with that and I've just been at home feeling sick. Also my husbands company picnic coming up and I'll prob feel too sick to go :( just feeling low right now. Anyone else?
