definately if you are able to admit that you need to go to the hospital you need to go. you dont need a professional to admit you. you can go voluntarily and the nice thing about that is that yu can leave when you want as well. if the hospital doesnt allow self admission than you can go thru your local emergency room. let your dad know. he sounds worried, let him know there is something to worry about and he will get you the help you need. on the basis of cutting alone is reason for admission. youre reaching out for help here, reach out where it really counts. youre really brave. take care of yourself.
