He left

I am going through SO much already.. a miscarriage.. now a breakup. He said it’s not healthy because we argue all the time and that maybe we can be together in a month or in the future. But the thing is- I needed him now...... I’m having so many bad thoughts about myself and I think the only thing keeping me alive is my 3 year old.

I don’t know what to do. I don’t know how to stop contacting him bawling my eyes out on the phone. He doesn’t want me anymore and I wish I could reverse it all. Someone please give me advice on what to do. This is the hardest breakup I’ve ever gone through.
