I have another job outside escorting for a few reasons. Massive one is cover for family and friends who don' know- I'm close to my family and they would get very worried and suspicious about it. Second is so I don't have to do either full time- because escorting involves a lot of making yourself do stuff (working on your profile, emails, advertising, etc), if I'm not very well (I am disabled) it can be very hard to make myself do those things, whereas the three days a week I have to go into work I don't have a choice if I'm not well (and if I'm depressed then I usually feel a bit better for making myself go and do stuff, if that makes sense?).
I don't want to do this for the rest of my life, I'm doing it to help me get through postgraduate education, so I also can't really afford to have massive gaps of employment on my CV either.
