CONSIDER: You are not bad. You are not doing bad. You are not being bad. You just cannot do/be everything for your dad anymore = a slave, a doormat, a live-in-maid, a spit bucket to regard with disgust, a "bad thing to complain about". You are you. Living at home taking care of others in these ways. And also living your life. Keep reaching out to others for support - if not T, how about other family members? There is often at least 1 OTHER person (that "cool but kinda faraway aunt/uncle/relative youve always liked") who feels the same way and could help out in some way.... You are not alone and i will keep you and your family in my thoughts and prayers
