Depression during Pregnancy

This is my second pregnancy . Already have a healthy 3 year old that I love more than anything. I was diagnosed with HG this pregnancy. I am week 13 today have been nauseous and throwing up all day long since week 6. It didnt get any better and got IV 6 times this month and 3 nausea medications did not work with me. Hearing so many infertility stories and my bestfriend is battling one . I feel so isolated and ashamed to tell those around me how much I hate being pregnant . I am tired and havent been able to do anything with my toddler . My hair is a mess and i look like a dead person the whole time. I cant have sex or enjoyed the company of my husband . And havent been able to leave the house since end of October. I feel awful not excited for the holidays or christmas or anything and covid and lockdowns have made it so much worse . I cant feel or enjoy my baby even though I had an ultrasound yesterday and heard a heartbeat. But felt nothing :( i feel sick, sad and angry
