Welcome to SR, Emma; very glad you found us.
I am so very sorry to hear of your experiences. I hope you do seek counseling to deal with the emotional and psychological effects of the rape; what happened to you is unthinkable and shattering; you deserve the much needed help to see you through the effects of this experience and assure that you have the resolution and skills to enter a healthy, successful, fulfilling and beautiful future.
It is very impressive and commendable that you are addressing your drinking at such a young age. There is a great life and world out there to be fully experienced - without the diminishment afforded by alcohol or substances.
Go for it, Emma; embrace sobriety and the true and beautiful Emma that lies within.
