A few weeks ago I lost my girlfriend whom I dated for over 3 years. She immediately started dating another guy. I haven't been in a happy place since then... and find it extremely hard to motivate myself to do any work, study, or even just get out of bed. I've been getting help for it, but I still just feel down all the time.. I was doing so good in school before, I don't want this to bring me down.. but it has been. Any advice?
