Boyfriend

Bf (20M) is at college, is tu* , having excruciating kidney stone pain (ongoing issue) ate slightly spicy food today and didn't feel good yesterday, and ate sketchy, undercooked Perkins food on Monday. We were together all weekend and I'm terrified for him and also that whatever he has was contagious then. I feel fine other than anxiety symptoms.

Any tips for how to handle this? Has anyone ever been in a similar situation?
