Hi
@MissEverything , welcome to SF. I'm sorry you feel neglected and like everyone's disappointed in you. You know, adults are imperfect beings. Some have issues of their own that make them neglect their kids, some don't know how to respond to their child's distress, and others just don't see any problem until it physically manifests in front of them (which is not okay at all. Prevention is better than cure.).
I wish you mom cared more about your feelings when you talk to her... but hurting yourself is not the solution. There are healthier (and more efficient) ways to get better, without anyone getting hurt. You have a full life in front of you, lots of changes ahead. I hope we can help you in your journey, you can always talk to us, we listen and care. Be kind to yourself, sweetheart.
