How to cope when spouse is filing for divorce.

Just wondering how some of you coped through the divorce process. We have a 7 month old but things have just really downward spiraled since having the baby and my husband is filing for divorce. I’m just so severely depressed and find it hard to take care of myself anymore. I’ve lost so much weight as food makes me sick to my stomach. I barely sleep from being sad and from our baby. My husband has moved out. He stops by to see the baby for about an hour each day. There was no cheating involved and there were wrong doings on both sides. I guess my husband has just had enough. I just want my family back :(
