Struggling

Fanatic_Reflection
I'm 17, almost 18. I'm underweight. I weighed 94.4 pounds today and I need to gain 15 pounds. I try to eat but it's hard when you don't have the right food in your house and you have anxiety and family issues. I'm scared I'll drop more. I've stayed at 95 for a long Time. This is the first time I weighed below 95. What should I do?
