Feeling so alone everything feels so heavy in my life right now it’s so unbearable!

I’m a mom of three I’m 35 years old. Two days after I come home from the hospital my husband hits me with news that were divorcing this was shocking to me. We only share one child together. I’m in the process of custody and divorce and this is the hardest thing I’ve ever had to do I’m currently back at home right now but I don’t know how I’m going to make it out of this. Sometimes it’s just so hard to have the strength to give my children all of me when I feel like I have nothing left. He was so bad I know it’s a blessing that it happened this way. He was controlling and he manipulated me and he was very emotionally abusive and he hit my children. Can anyone relate
