Re: What do i do?
I am so sorry you are going through this...and even more sorry that you do not feel your mother will be able to offer you the support you need from her right now.
I would still encourage you to discuss your feelings and fears with her. I would make yourself an appointment with your doctor and discuss your situation with him/her as well, and as soon as possible. There are short term medication you could take to get you through your graduation. Once you have gotten through that, you can go back and seek other more long term treatment.
I encourage you to look at this as something treatable, and something you can overcome with the proper help. And no need for any embarrassment either, Many people your age start with feelings such as yours at major turning points in their lives and left untreated can cause problems down the line that are much more difficult to overcome.
Please take this opportunity to listen to your body trying to give you messages, and follow through until you feel better. As you enter your adult life, taking charge of you health is something you will need to take over for yourself. I wish you the best, and please come back and let us know how you are doing...I am interested in what happens, and your story will help others who are going through similar issues right now.
Another thing to remember, you are not alone...Just knowing that can be enough to really help get yourself on your way to recovery and a happy life ahead.
