In the US you could possibly have a claim against the employer where the old businessman sent you a text (if you saved it), which might help with your money issues. I do not know about the British law. I would think they would have some sort of recourse as well.

Your writing shows "low emotional libido" - you write of things that one would expect to cause an emotional reaction, such as, for example, your feeling that you are being used as an object, but the writing is very flat. Sexuality is just another drive, another aspect of emotional life. Maybe you need a fix - maybe a low dose antidepressant or a creative outlet, or something (not alcohol) that ignites you. If you do not treat sexuality as specific, but instead treat it as one type of a general problem with emotionality, it could kill more than one bird.
