If my employer hurt me emotionally.....should I?

I left my job 6 months ago because I was hurt by my employers son. Long story, but I never got the decency of an apology. During the 6 months I had a nervous breakdown and suffered from depression. I am much, much better now. The parents do not want to even acknowledge what their son did and have ignored everything that I have gone through. We were very close and I just recently cut them of completely. I don't understand why they won't give an apology. I don't think I would have suffered like I did if an apology was given. Also, you would think that they would be smart enough to do so knowing what I know about them. All I would have to do is make a phone call to an insurance company. People tell me I should make those phone calls and as bad as I feel, sometimes I want to. But the other part of me says leave it alone. The thing is, the son (who is 29) keeps behaving the way he does over and over again and is never held accountable for his actions. What do you think I should do? Filing for workers' comp or disability is out of the question. I am not up for that. But I feel he should pay for what he has done.
