the past few weeks I realized I'm having anxiety attacks during the last week of my relationship till now. We broke up a week ago. My chest hurts so much, I'm breathing but I'm more likely Sighing instead of exhaling, im hyperventilating. I have not had any appetite since then, and yesterday I found out she started talking and hanging out with another co worker until super late at night. I'm been excessively worrying about her safety even now that we broke up. Since then I have not eaten anything in 24hours or so. I just feel so weak and sleepy all the time
