pregnant with #2 & I think I am depressed

hello.. I have an amazing 15 month old daughter already and a great hubby. I'm currently 9 weeks pregnant with my second and I'm SO nauseous and sick 24/7. it was the same with my daughter and I remember sort of feeling a sense of depression because of the constant nausea and also not feeling like myself and I feel the exact same way with this pregnancy but I feel like it's worst since having more responsibilities by caring for a toddler. I just feel hopeless, useless, feel like I constantly want to throw up, I feel like an animal in survival mode and it's putting a lot of strain on my relationship.. I know it'll pass (hopefully lol) once first trimester is done but omg what do I do... I even take Diclectin pills to help with nausea but honestly it just keeps vomiting at bay (still throw up occasionally) but nausea is still always there. always. I can't cook or smell food cooking. it's just horriblej and I just feel I'm in a funk that seems like it'll never get better.. I am always so emotional.. 😭😭
