this types of things are common here in us. The foremost thing is not to PANIK, it will bring down the hell out of u. U gotta seek help from anyone , may be it be from library personnel, church, temple, anyone, may be even with meetup group,
common u r in usa , and u dont need a friend from school or college to be your friends, u can simply join any social networking group and find ppl of your interest and share your stories

they can be of your best help, dont think you are alone, just join meetup group, u can find hundreds of ppl with similiar type of situation and they might channelized your positive energy in the better well being, just dont think u r alone or u dont hv buddies

or just volunteer in church in sundays or saturdays in their daily activities,in that u can connect to the commnities, one thing ppl misnderstood abt church is that it is not only for praying, but also getting connted with different wake of life.
Just remove the sterotype feelings that u dont hv drinking buddies or shopping buddies, just go out, u will shine for life.
