Sensing Girlfriend's Emotions Practically 24-7

Just to give some background I'm Paul, if you'd like to call me by that. Average high school Catholic school boy.

My story: When I began high school, I met a girl who was out of the ordinary, who told me of strange dreams and how she could 'feel' other people's emotions, including mine, while we talked and even, after we were very closely bonded, when we weren't together. I never heard of any of this before but I kept an open mind. After awhile, I began to develop a sense of different people's emotions much better. She is no longer a large part of my life, however, I am now able to sense every emotion, basically, that my girlfriend feels. Whether I am with her or not, I feel if she gets nervous, anxious, hyper, sad, and I can tell almost all the time when she falls asleep. I can tell if she awakes in the middle of the night or is up late and cannot sleep, because often times, I am doing the same due to her emotions.

I love my girlfriend, I like being able to feel her emotions because I get to share them with her, and if she is upset, I can tell if she is getting happier, or if she is not, I know to help her more and more. However, her emotions are beginning to 'override' mine per se, and when I am happy and she is sad, I lose track of my happiness. I can't be happy and sad at the same time, well... I guess I can be, but it gets to be stressful to say the least. And if I'm sad because of her sadness, how am I of help to her? To anyone?

How can I better control this WITHOUT losing this ability, can I form a sort of on/off switch to help me, or is there just a better way to get my emotions back on the forefront while feeling hers almost distantly but still enough to be readable?
