I have pulled away from almost everyone over the last year and now I do not know how to come back. Where do I even start?

“And he came thither unto a cave, and lodged there; and, behold, the word of the LORD came to him, and he said unto him, What doest thou here, Elijah? And he said, I have been very jealous for the LORD God of hosts: for the children of Israel have forsaken thy covenant, thrown down thine altars, and slain thy prophets with the sword; and I, even I only, am left; and they seek my life, to take it away.”

Elijah had just won a public showdown on Mount Carmel, then ran for his life into the desert and ended up in a cave convinced he was the only faithful person left. He was wrong about that, and God does not begin by correcting him. A question comes first, then food and sleep, then company and work. Scripture treats isolation as something to be gently walked out of, not scolded away.

“Nevertheless God, that comforteth those that are cast down, comforted us by the coming of Titus;”

Paul is describing a stretch when he was worn down on every side, and he says God comforted him by the coming of Titus. Not by a vision, not by a rescue: by a friend arriving. Paul, who wrote much of the New Testament, needed a person to show up in the room. That is worth holding onto if you have started to believe that needing people is a weakness in you.
