Pregnant and stressed

My child's father decided not to be in our lives a couple weeks ago.. I'm 14 weeks today .. I thought I was over it until I saw he is now back with his other baby's mother and now posting his kid all on social media.. I'm guessing he was cheating the entire time we were together... I thought I got over it but I guess not. Today I just starting throwing up from being so stressed out and crying non stop ...... Any encouraging words or things I can do to get my mind off of this bullshit ? (Excuse my language) 😰😔
