Have you tried going to you mom and talking to her about this? I'm sure your mother doesn't hate you, you are her daughter. If not her try going to your school consular.. and talk to him or her about how you are feeling. You may not believe it but if your feeling this bad about yourself you do need professional help Espically if your putting harm on yourself like cutting. It doesn't resolve anything but leave ugly scars on your body, trust me been there done that. You can be happy. You just have to chose to be. Find new friends in school, it might be hard, but having more people to talk to and keep your mind occupated can get your mind off of things, also try some sports, to get stress off your shoulders and to get some anger out. I found joining the swim team REALLY helped me out a lot and the best part about it I became one of the best on my team. But I really think you should talk to your mom or your counseler about this issues your having and grief about your father. It will really help you look up in this world. Middle and high school are tough times, but you wanna make sure your focused during them so you can make a good life for your self in the real world. Just give it a try talk to an adult. It can honestly really help you, believe me I've been in ur shoes.
Thanks....I made and appointment with my councilor ...and it's not that I don't have friends its just even tho so many people r around me no one really understands me...and I'm hated by some people for no reason...my school doesn't exactly give you much freedom ...it's really strict and some teachers don't even care about you feelings...I gonna try to stop cutting...
