Bad breakup

Broke up with my boyfriend of what would’ve been 7 years this November. We have a almost 4 month old and I recently find out I’m pregnant. I’m been feeling so depressed crying on and off since yesterday. I don’t know what to do. I haven’t had a meltdown this bad in years and I’m trying to stay storm for my daughter but I feel so helpless. I was recently diagnosed with ppd. Please give me advice on how to get over it. I loved him so much but we were bad for each other.
