Ever since I was 12, I've always been the person people struggling with depression or other emotional issues turn to. I'm usually good at giving at advice and listening, but I have a problem with being dragged down along with it or believe it's my duty to fix it... Currently, I'm a college student in a long distance relationship with my pessimistic girlfriend. A few months ago, it was discovered that she cheated on me(by way of kissing) with another girl. I still struggle today with trusting her, but she's promised that it's all behind her now. We're still living apart and I'm trying my hardest to keep positive, but her world is crashing in on her. She isnt doing well in school and isn't motivated to try to achieve, has minimal friends she can count on and spends most of her time in bed. I'm typically a positive person, but I find myself trying to help her and end up getting dragged down with her. How do I keep myself happy and strong, while trying to help her.. Any advice?
