I don't know what else to do but I am so sick and now have chronic fatigue and constipation on top of a autoimmune disease and diagnosed with HG. 
This pregnancy is kicking my but & I have been in bed for literally 3 months
Now I feel overwhelmed and unenthusiastic about my pregnancy. My hubby understands but doesn't grasp how bad I feel.
I think I'm depressed and don't know what to do.. I told my doctor who said it hormones and I know it's more. I just don't feel happy at all -ever 
Please don't reply with hate.. I'm really fradgile
