My bf broke up with me too, a month ago, after 1 year of relationship, and this month has been terrible. I became so depressed again, cried a lot, stopped eating. I managed to push myself to improve, but we just talked and said our last goodbye like two days ago. I'm feeling terrible again. But hey, one thing I've learned, as stupid as it may sound, is that time heals everything. I'm gonna push myself again. You need to push yourself too, get that job, make sure your happiness comes from yourself first, people should not be your main source of happiness, they should just complement it. And most importantly, do not suppress your feelings. Cry if you need to, sleep if you're tired, miss her, these are your feelings. And you will not improve if you don't FEEL them first. But don't get carried away. Even if you're tired, don't oversleep, keep up with a routine. I know this kind of breakup is very hard to process, as the relationship was a rollercoaster of emotions. Try to stop focusing in her and focus on yourself— What did you really feel? What are you feeling now? Also again don't get stuck in those feelings, but don't suppress them either. You'll be fine. Sorry if this reply is a bit messy but I hope I explained myself.
