Pain & suicidal thoughts

I’ve been through so much over the past 2 years. My son has went through more & I feel that it’s because of me. Sometimes I feel like it’s best for him to be without me. I’ve thought about suicide a lot lately. My ex husband broke me in ways I didn’t know was possible. Everything is always my fault. I’m the reason he can’t be a daddy. I haven’t ever kept him away from his child. My child suffers so much. I’m trying to hold on to life. I don’t won’t my son to see me like this. I’m very depressed & don’t feel like no one can help me.
