The way to tell them is to screenshot this YikYak post to show them how ashamed, scared, and sad you are. You love them and don't want to disappoint them and you value what they have sacrificed to help you. You need more help. You want to ask them for more help. You dont know what went wrong, you dont know if you'll ever get it right. You wish you could just fix it yourself, but here you are. Idk your parents but if you were my child... I'd smile and ask you "Why do we fall?" and offer my hand
