"Sweetie, there is nothing 'wrong' with you in the sense of being a bad person. You are a person who survived hard things and is now looking for the love you missed. However, what you are feeling is called 'Anxious Attachment.' When we don't get stability from our parents, we try to grab onto anyone who gives us attention, even if it hurts us. At 16, your heart is still growing, and being with someone 22 who has 'complicated' issues is a huge weight for you to carry. Your body is getting sick because it’s trying to tell you that you don't feel safe. Please, be kind to yourself. You don't need a boyfriend right now; you need healing and to learn how to love yourself first. You are not 'broken,' you are just overwhelmed. Sending you hugs."
