I am sorry about what happened to you. My old master was a lot like that. It was the main reason why I left him. You should talk to your master and tell him your feelings.

I must say that your master was indeed irresponsible. He took advantage of one of your weaknesses and exploited it. A master must respect his sub and care for them as well. He or she should protect them physically and mentally. The master's greatest joy should be the well being of his/her slave or sub.
