Sweet RA,
People often develop depression after the loss of a loved one. This is a normal reaction to losing someone who was so important to you. You can get help and you can feel better. You will always miss him, he will always be a part of you but you are still alive and are meant to be. Please get some help. Tell you parents or your school counsoler how you feel. They will help you as you grieve for you boyfriend. Also keep coming here, most of us have lived with depression and the feelings you are experiencing right now. We do understand the depth of the pain and the struggle to get better.
Take care dear one,
Carrie
