Depression and anxiety

I have had depression and anxiety my entire life and typically it’s manageable. I am currently 28 weeks and the past couple weeks im noticeably lazier but recently the past couple days im just so full of anxiety about being a new parent and get so overwhelmed. I barely go to work and basically am the full provider in my family so we are suffering and I just feel like im failing and I dont know what to do or how to help myself. Everybody is saying I should begin the nesting stage but lately i just feel so rushed coming near the end of my pregnancy I really dont know what to do. I know theres a problem and want to fix it I just need help. 😥
