Your time with a Swift Mentor was not really a "Horror Story". It sounds like what 100's of students at big trucking companies experience everyday.
You really should call Swift's training department and see if you can get another mentor and finish your training with them. After you get at least 3 months experience under your belt, you can then go to a better company if you like.
Right now, your options a very limited in the OTR world. If you do get another company to hire you, then you will have to go out with another trainer and start ALL over again. :sad: If you somehow can get your job back at Swift at least you will get credit for the time that you already spent with your 1st trainer. Once you get your own truck, life will get a little better.
