Post grad depression and health issues

Graduated from college in May and had panic attacks for months before and after. It felt like the worst “breakup/death” in my life. I loved my college, my friends, town,community, etc so much. Changed my life for the better and was the best two years of my life. I was so depressed after graduation my body just shut off and became emotionally numb. It’s hitting me harder now that I see everyone go back to school, even my new favorite co workers went back. I absolutely hate my toxic job, toxic home town and living situation. I’m having serious health issues again and not sure how to handle this all. Any suggestions? It sounds stupid but I was so in love with everything in my life and now it’s the complete opposite and it physically hurts.
