I think you are being too nice. They have served you very poorly and I don't know if it is helpful to make any excuses or tell everyone how you are. This should have been figured out before they hired. Now, maybe you should not have put all the eggs in this startup basket. I hope you are able to find another position in the area, do t stop trying. Next to e, give yourself time to be "excited" and tell everyone about a new thing.
