Having emotional outbursts every day

If not twice a day. I literally can't control my emotions at all. I cry over everything and stress myself out and yell at people for no reason, fight with my loved ones, and I know it's not good for me or the baby. I've started to hate myself. It's like I don't even know who I am anymore and I hate it I've ALWAYS been an emotional and sensitive person and struggled with depression and anxiety, so crying a lot and being stressed is normal, but not this much, and not mood swings to this extreme. 
Idk what to do. I've tried deep breaths and usually my boyfriend can calm me down but he's leaving for a month and I honestly don't know how I'll survive without him. Anyone else struggling with their emotions...
