You are 20. If you feel this way about it stop now. I started at 19 and if I had stopped at 20 I wouldn't have found myself working in a call centre for minimum wage when I was 30.
It doesn't sound like the job is for you, I spent my 20s mostly drunk, paranoid about clients, often skint and taking bookings I wouldn't normally.
By fluke I found a job that I am very good at through a friend and I'm doing OK now and do the odd booking here and there to supplement my wages. But it isn't a job for me full time, I like the routine of 9-5 and I feel some self worth now. But when I quit for a year age 30, I realised I had absolutely no work experience and no prospects until said fluke. Work part time or study part time, if you absolutely have to escort then you won't hate it as much. Youre young enough to change direction if that is what you wish x
