Emotional/mental stress

How harmful is emotional stress and yelling on a pregnancy . I’m almost 7 months pregnant and my entire pregnancy has been filled with some pretty heavy things . Finical issues , family issues , fighting with my husband at times which involved some yelling . Lately my kids haven’t been listening to me and I’ll end up yelling a lot . I hate yelling I hate the loudness , always have and I hate how it makes me feel . It just seems like they will not listen if I don’t . I’m really starting to get concerned about my baby . There’s been issues where my heart races , I’ll start shaking , and at times when I cry I’ll feel like I’m hyperventilating , my eyes feel like they are always twitching . I try to not let things get so heated and escalated . My pregnancy is already high risk for multiple reasons .
