I suffer from PTSD and depression and it makes it difficult for me to hold down a "normal" job.
I can usually make it in to work in this job, which is good, but it has taken time, because I have "trained" myself to keep myself safe, not to get riled by idiots and disrespectful types and know that their attitudes are their own and not mine. If a client is polite, clean and respectful of my boundaries then I don't mind the job and I be myself a bit, but if I encounter someone even slightly disrespectful then I just take their money and get into my work "persona" and I take no shit from them. I just see it as money. But it seems to take a good while to get to this point in your escorting career!
This job is good for the lack of pressure. Like someone else said, if I feel down and not up to work then I just switch my phone off and hide away. When I feel better I stick up "available today" and put up my ads and work. I don't have a boss / demanding co-workers / deadlines or anything like that.
It can be good for money and flexible, but make sure you take care of your mental health too and if you start feeling any kind of horrible feeling about this work then make sure you get it addressed (speak to someone you trust, get counselling, go to a sex work project etc).
