My heart goes out to you. How stressful and disappointing! I've been trying to find any kind of medical assistance the past couple months as well, and I am absolutely appalled by the lack of mental health resources. It's like the rest of world doesn't understand how very important it is.
The local health department might have resources. Sometimes inpatient psychiatric hospitals will know of organizations that offer emergency counseling services. Also your local Salvation Army might know. If you're religious, a church is a good place to go as well. If it gets too much and you feel like you're really going to fall apart crisis hotlines are always an option.
You and your cat are going to be just fine. Hang in there. School may be starting later than preferred, but you'll be there before you know it. You can always come here and vent (you definitely deserve to!).
