stress and high anxiety!!!

Has anyone else suffered with depression,stress and high anxity while pregnant?? I am not on any meds for it but it's  seriously ruining my life!!! As soon as I wake up I feel like I can't breathe and it's like this all day. I am always on edge..I have three kids ages 9,8, and 6 and my oldest has autism so it's very stressful at times.I am also a stay at home mom with no social life!! All I have is family I literally have no friends bc I moved to a different state a couple years ago and with me having kids I don't get out much only to go grocery shopping.....my fiancé and family is all I have:( I just feel alone. My fiancé and i haven't been getting a long so well lately and me being pregnant and hormonal I've been very emotional crying about everything😞 I feel like I am hurting my unborn baby by being like this I really don't know what to do bc I can't control this feeling and it's killings me😢😢
