Severe stress and anxiety?

I’ve been in an extremely stressful family environment and there’s honestly nothing I can do about it right this second, soemtimes I’m really calm and happy and there like 3-4 times a week I’m put into panic attacks and stress mode

Is this likely to harm the baby? I’m so worried. I’m 9 weeks and want this baby more than anything. I just get scared baby is gonna leave me because I’ve been so anxious and fighting so much.

Please give me some reassurance ❤️
