First of all, DO NOT PANICKPANIC; life has a mysterious way of sorting things out.
If I were in your situation, I would :
- Change your CV information, i.e., email and phone number, and do not have it on any public job sites,sites; only apply directly to jobs you are interested in.
- Find references you can trust, and that will not lead any new interviewers to your old boss.
- When you do have an interview, be sneaky,: let it slip to an employee you know will speak with your old boss, and brag about it, say you have a fantastic opportunity with company A, when you are really interviewing with company B, send. Send this snake of a boss down the wrong path.
- Finally, when YOU DO FIND A NEW JOB (and you will), just leave as quietly as you can and put this horrible experience behind you.
