Never written before

Good morning, just wanted to say hello to everyone. I've jumped on board to heop fully get advice or perhaps a read over of my first proper attempt at writing. It's essentially a memoir but I've only managed 13,000 words so far. My hope was to publish it as an ebook and even if 100 people downloaded it and read it I would consider it a success. But I have no idea if my little story would be of interest to anyone. Bit of a miserable story of my depression and finding out my ex at the time who was a teacher was sleeping with one of her pupils.
Any pointers would be gratefully received. Thanks in advance.
