A few ideas off the top of my head, again the webcam option, which is not illegal but your image would be out there on the internet forever.
Next, Wait Tables, even though I know your an introvert, it could help build your skin and skills with dealing with the public.
Ultimately, I'd recommend stop judging and tell your ego to take a step aside. Why are you allowing an idea to perpetuate whom you are? If your lost, do anything to look for ideas, even if its something you don't like, because it may then lead you to something you do. Be Grateful for what you have and can do, while setting the intention to do something greater or better.
One of the first steps is to identify what you wish to do. I think you wanted to escort because it put you at a expected high level of income doing something you enjoy. I found an article about a major male porn start the other day and he says he risks his health every single day, and he makes protecting it his number one priority.
The job isn't whats stopping you, its what you think about the job. Here is something else I've noticed, your angry about people judging escorts and prostitution, why not the same level of anger of judging admin assistants? Notice where you also make judgement of other people instead of seeing whom they are.
There is also jobs like Social Media Managers, and whom knows what else out there that didn't exist ten years ago. I myself am interested in Dome houses, which to get to that point I'll have to wait and save money, and learn.
If you need to borrow money check out Personal Loans and Online Investing - Peer to Peer Lending - Prosper
, or find out about student loans or aid, which I'll likely be doing before too long myself.
Another thing you might look into is a book called Strength Finder 2.0. Book has a key in it to take a Gallup test to see where your strengths lie within 37 major themes, and the book itself is like a hard copy of their descriptions. Its about $14 on amazon last time I checked. I'll be interested to know what themes you have, I suspect we may have one or two that are similar.
