12 weeks with a slight depression

I'm 12 weeks now. Backache, no appetite, can't sleep well, sensitive to smell, dry vomit and exhausted. I Can't eat much but still gained 3 kg during my first trimester; my body size is expanding quickly, had to buy a new bra and maternity dress. Somehow I feel a slight bit depressed, like I have wasted my 2 months doing nothing like a useless person. Since week 5, I have spent most of my time in bed, like 20 hours a day, due to nausea, dizziness, headache etc. I can't walk much and can't sit for a long time. I cried a few times, l felt so lonely that I can't share my feeling to anyone. As I was trying to share my feelings with my husband and my mom, their reply was always, "Continue to stay on the bed; you need more rest".. Husband kept telling me he couldn't understand how I felt, how suffered I was, but I know he's been trying hard to calm me down. To all the mummy out there, wondering when is this going to end? I can't wait for short jogging, at least some exercise makes me feel like I'm more like a normal person. I'm going for NIPT and Oscar test tomorrow; hopefully, everything goes well. To my baby, no matter how suffered mummy was but I will never leave you. Mummy loves you and counting down the days to May 2022. ♥️
