I want to do it again

So I’ve been sucidal in the past and I really want to hurt myself again. My friends are leaving me because they are making me pick sides. I don’t want to pick sides because I want to be friends with them all. A month ago my friend told me that she asked to come over and her mom said no because her mom thought mine had a bad reputation and that she was a bad parent. So “friend” is getting mad at me because she is going to get grounded because I told my mom that. I had no choice! My mom asked me why my friend couldn’t come over!! I couldn’t lie! My mom was getting threatened and beat behind closed doors because she was in an abusive relationship for over a year so it made her act different but my mom and her mom never even met!!!! idk what to do!!! Help?

EDIT!!- so I messaged her a long paragraph telling her that it’s not my fault etc etc, but she opened it and screenshoted but I didn’t reply. So I asked why she screenshoted IT WAS HER MOM!!! I don’t know what to do now! I was cursing and stuff And this particular friends mom ABSOLUTELY hates when people curse!!!
