If people do not care, you need to see that the Lord cares and He is the only One that matters. That does not make rejection easier, but the Lord hears you when no one else does. The Lord sees your pain, even when others do not. Please do not give up hope. When people fail you, that's when you should turn to the Lord most, because He never will let you down. Give this thing over to the Lord and trust Him to bring you through--not people.
