I am praying for your mother. You can only do so much. If she is suffering mentally, she needs to seek help too. You are not her therapist or caregiver. If it’s true she can’t handle your breakdown, then remember now to have boundaries in discussing it with her. Focusing on yourself will actually ease her suffering. If she sees you doing better, she may feel better too. I don’t mean for you to become codependent, but it sounds like she is codependent on you. release it to God. This is rock bottom but it’s not the end. I praying for you both. Don’t give up. I believe in you both. She just needs time to process everything and life.
