I talk to my husband or my friend about how I’m feeling so they can help me process it. I don’t think there’s any one right answer, you’ll go through more emotions you thought you knew you could. You’re sad, you wonder what you did wrong, what you missed, what you should have done differently, whether you failed them. Then you might get angry. Maybe the anger never stops. I don’t know. Maybe you want to change your name and leave so you don’t have to face what your DE sibling is doing in front of you and knowing there’s nothing you can do to stop them. I don’t know. I’m not an expert.
