My world turned upside down

So it’s been a rough weekend for me. Friday night my boyfriend/baby daddy, decided he didn’t want to be with me and left me for another girl. This crushed me completely and has put me in a big depression.

I don’t know what to do. I have my daughter to think about but I can’t stop wanting him to come back to us. He’s openly said he loves me and he misses me, but has no reason or answer as to why he won’t come back.

I need some words of encouragement.

How do I focus on my health for my baby when my happiness is with him? I’m so broken. I’m so tired. I’m so alone. This is literally me all day.
