I guess you could write one and hand it over to a publisher? It takes money and loads of time, but if you could find someone who would support you and give you advices, I'm sure you'll be fine. If you don't work yet, start looking for a part-time job (or a full one if you aren't a student but I take you are?) and save up for this so you can say you have a somewhat stable job. Once you hand over the raws, make sure you give it to a person who do not take the credits away from you. So find out who is the most trusted publisher in your area, try to get in contact with them and asked what to do in this situation, so you can have a clearer picture about how this works. It takes so much time, but I honestly advise you to go after your dreams and be an author if you would like to be one. :)
Thanks a lot for this wonderful advice. I will definitely keep this in mind
