Writer's Fallout Shelter

Hi, I hope this is the correct place to post this, if not I apologise. I was just wondering if any of you guys experience this and if so how do you deal with it. I've wanted to be a writer for a long time now. I've started and abandoned many stories due to self doubt. I would get so far and then realise that I had no idea where this story was going, no clear idea of how it would end and with that realisation I would starting doubting my ability and usually abandon the effort. This has happened many times. and often it has been years before I could bring my self to try again. The feelings that I am a fraud are just to strong. This is a major problem for me and any help, guidence or suggestions really would be appreciated.
