severely stressed and upset whole pregnancy?

My whole pregnancy has probably been the roughest time of my life and I feel as though I haven't even enjoyed it, my parter wanted me to get an abortion at first and then ended up leaving me and coming back and then cheated on me countless times and I probably balled my eyes out to sleep almost every single night up until 8 months 😔 I'm so worried something is going to be wrong with my baby. Please guys any information or personal experience?
