Is it worth suing my employer and/or ex partner for damages?

I have always had a sterling work record, both ethically and in terms of delivering results. Recently however, and following a very nasty break-up with my ex partner, he has made false claims of financial misconduct about me to my employer and even went so far as to produce false evidence to proof the case. This resulted in a protracted investigation and disciplinary process. After 4 gruelling days of hearings, current status is that it now seems to be accepted by all that there were no grounds for the allegations of misconduct and that my name should be cleared completely. However, the year of anguish and extreme invasion in my personal life has left its mark to the extent that I had to be hospitalized for the ongoing trauma, notwithstanding the exorbitant legal fees that I had to absorb (I can buy a car for cash with the money that I've lost). I am still awaiting the final ruling and am not sure if this will include a cost ruling - frankly, I'm not sure if the chairperson liked me and he may even be thinking "where there's smoke there's fire", and "punish" me by not awarding costs. (I am paranoid, I know, but after a year of watching my back, I don't quite know how else to operate). But, question is, if it does not stipulate a cost ruling, how advisable is it to sue either my employer and/or my ex-partner for the malicious and protracted financial and emotional damage?
