You have the first and most important prerequisite to be an escort, a dysfunctional relationship with your father. I will assume that you will ignore all the good advice and proceed with your plans
If you do start, the most important thing is to have an exit plan. You need to work for a limited period of time to finance a college course or some business that will give you a reasonable income and self-respect. Money, or rather the ability to spend it, is as addictive as any drug. Resist this along with the other drugs that you will be able to afford.
If you can, go for a complete makeover and move to a different city, if not a different country. Some of the most successful escorts that I have come across have seen themselves as an actress playing a role.
If you have some idea of ending up as part of a happy family in the future, you will not get there from where your mind is now without serious counselling. Start this as soon as you can and begin to heal the hurt inside you. Learn to love and respect yourself and to understand and forgive the limitations of those around you.
Be safe. If you have the slightest doubt, do not take any chances with your health or safety, no matter how much money is on offer.
Finally, enjoy your life and forgive me for lecturing like this, it comes with old age.
