i would say definitely to escort.
If you feel feel repulsion servicing men, then its acceptable and you might consider to leave the sex world behind.
However if its because of the few trying to harass you, then if i was you I would continue doing what i have always been doing.
Thinking and talking to kill someone its very easy, but not a simple task to carry out.
That chap obviously was having a bad day, and probably living a lonely life, so he used you to express his anger, because you were the most recent soul he met.
Also in my personal opinion when something happens to you, make it in the "third person".
Supposing that your name is flame, then when you have a bad customer, you should say to yourself, "Look at that ! they made Flame upset today" am going to talk to her now, and reassure her all is good all is fine.
You achieve a kind of detachment in this way.
I receive threats every week, and if some weeks are perfectly fine, i start thinking that something is wrong. The verbal abuse and text/sms, are mostly complaints about myself not willing to lower my rates, and guess who thay are? But thats happening to jenny, and the real me reports their number and details to the Ugly Mug Scheme. They are wonderful and so so helpful.
Also Here in Uk it is quite difficult to seriously make an attempt to someone's life, going to shopping in central london we get photographed at least 300 times in one day.
Landmark, landmark, if you meet anyone make them stand by the tube station, pub, chicken shop,,,,
Its all normall keep it up
