I'm working on a story, and I'm having trouble coming up with an ending. I'm used to writing faster-paced stories, and this one is more character based, I guess, than plot-based. Here is the ridiculously shortened version. Alex, the MC, is a 28/29 year old working an unsatisfying desk job. He's a manic depressive insomniac who'll do anything to get some, any, sleep. Including popping Oxycodone and drowning himself in alcohol. But everything changes when he finds a young woman sleeping in the back of his car. When he shoos her away, she doesn't respond, and he comes to realize that she's nearly catatonic. For reasons I havent quite worked out yet, he takes her in and names her Wander. As he begins to care for her and tries to help her regain herself, he starts losing his dependency on alcohol and drugs. His best friend Tony is convinced that Wander is an angel sent to help Alex. Now, Wander and Alex's relationship is in no way romantic. Like I said, I dont know yet why Alex takes her in, but I DO have it worked out why she's catatonic. I guess the main thing I'm asking is, does anyone have any ideas about what kind of conflict I should include in the story? Wander doesn't "come around" until very near the end, and I'm not sure if I want that to be the ending, or what... OKAY. Here's my question: Should I add more of an outside conflict, or would you reccommend that I keep it a story just about the characters?
