That's how I was all day today and part of my work day, I was crying in front of my boss on the floor and it was terrible, I just went into the bathroom and cried and felt terrible, but then I decided instead of going home and feeling even more lonely and isolated I stuck it out at work and I felt better probably because I was around people. Maybe that will help you out, just force yourself to be around people if you are able to. Hopefully you feel better tomorrow, I hope this has helped you a little. Good luck !
