The answer as to whether you qualify for unemployment will depend on whether you can prove you were forced to resign. What would they have done to you if you did not resign? Let you go? That actually would have been preferable when it comes to collecting unemployment. You would have been let go for a reason other than having done something directly against your employer's interest.
If you have a discrimination theory about retaliatory discharge or hostile workplace conditions you'll need a lawyer. Religious belief, age, gender, race etc. all are discriminatory reasons for which you cannot be legally fired and upon which you might base a wrongful termination suit.
If you are an at-will employee, you can be fired for any reason or no reason, except unlawful discrimination. If you do not have an employment contract or union to represent you, your recourse is limited. Discrimination based on age, gender, race, religious beliefs etc.... may give rise to a different answer.
