Someone please help me. I’m so desperate

Currently 8 weeks pregnant with baby #2 and my first will be 2 this month. I am 100% not ready for another child but my husband is divorcing me if I terminate. Can someone anyone please help me and give me some advice. I have no one to talk to. All I do is cry, I am so depressed and anxious. I wake up in the morning in a panic with my heart beating so fast every single day. I truly don’t know what to do. I’m so desperate… I can’t do this. We have been together 10 years and married 4. I’m so alone but I can’t have another child
