Pregnant and depressed

I really don’t want to cry but I cannot stop. I cannot stress and my doctor already told me my blood pressure was to high.. idk what to do. I want my baby to be healthy but I can’t stop crying and stressing myself out. Every time I get in front of my mom or anyone I cry.. I don’t want to stress my baby out but it’s so hard.. any advice? Anyone been depressed while pregnant before? My so just broke up with me and said he was moving on and gonna talk to other girls and of course I’m upset.. he’s acting really nasty towards me and blocked me also.. this is the wrong time for me to be in this situation and it sucks
