Local churches in Dehradun probably don’t have structured programs for Greyhound tickets (that’s more of a U.S. thing), but you’ve got options:
Start by calling a local helpline (India’s version of “211”) or visiting nonprofit shelters, some NGOs, or community groups that help with travel fares when you’re in a bind.
Check with larger organizations like Catholic Charities or St. Vincent de Paul in bigger cities; they sometimes help with bus fare or refer you.
If you’re under 21, look into Greyhound’s “Home Free” (U.S. only) program for youth in trouble, worth knowing about if you ever travel abroad.
No straightforward church help around here, but local NGOs, shelters, and community helplines are your best bet.
