I can't stop cutting

Maybe seek help? Or tell someone you are close to . My own best friend left me without a reason too and for the longest time i felt bad and blamed myself . But if she left you without a reason then you should be instead mad at her for not telling you the reason why . You deserve an explanation from her . Ive long since sort of got over the trauma ( I’d call it for myself) of her leaving me . But yeah , dont blame yourself .
